Base interface class for CellMesh type plugins.
This Cell Mesh interface builds upon the Mesh interface to add the concept of cells to the previous mesh type (which only stored nodes).
In this implementation, a cell is defined by a set of nodes defined in a particualr order known by the cell type.
Meshes can have heterogeneous cells and each cell can be bound to many property sets and to many attributes. In the same spirit as attributes are handled in GmMesh, the default GmCellMesh implementation includes a service to store and dynamically add attributes to cells. See GmMesh class comments for details.
If a mesh is bound to more than one property set, there should be no property id that belongs to both property sets (no name clashes).
The main differences between property sets and attributes are:
| GmCellMesh::GmCellMesh | ( | GmSimulationData * | simulation, |
| QString | id, | ||
| QString | description, | ||
| const GmLogCategory & | logger ) |
Constructor.
| simulation | Reference to the simulation object. |
| id | Mesh id. |
| description | Mesh description. |
| logger | Plugin logger object used to emmit messages |
|
pure virtual |
Informs the mesh that a cell had its active state changed, being made active / inactive. Called by GmCell::setactive()
This function should be reimplemented by mesh implementations to update the number of active cells in the mesh.
|
inlinevirtual |
Adds a new (empty) cell group to the mesh.
This function should be reimplemented by mesh implementations that support the mesh cell group edition capability (hasCapability("editGroups") returns true).
On success, it returns the new group index (the group index in the list returned by cellGroupIds()). On error, returns -1.
|
inlinevirtual |
Adds new cells to the mesh, WHITHOUT initializing their nodes or attributes.
The numCellTypes parameter should be a list with size equal to GM_NUM_CELL_TYPES, where each entry defines the number of elements of the respective type that will be added to the mesh.
The new cells should be created in the order defined by the GmCellType enumeration, i.e, if the numCellTypes list defines that we want 10 new QUAD4 elements and 20 new TRI3 elements, all the QUAD4 elements should be added before the TRI3 elements since QUAD4 appears before TRI3 in the enumeration. This allows for the user to know that the first 10 new elements are quads and the next 20 are triangles.
This function should be reimplemented by mesh implementations that support mesh edition (hasCapability("addCells") returns true). It should increase the internal space used for cells. Cell nodes and properties will be later filled by the USER with calls to the appropriate functions in GmCell. If the cells have attributes, this function should also make sure that those value sets are re-dimensioned and the new values initialised with value defaults. When dealing with Element meshes, that might include re-dimensioning Gauss indices.
VERY IMPORTANT: The cell might be in an unstable state before nodes and properties are properly set by calls to GmCell::setNodes() and GmCell::setProperties(), and so calling ANY other function in the cell before that can lead to unpredictable results.
On error, this function should leave the mesh unchanged and return -1. On success, it should return the index of the first new cell. If called with a total number of cells equal to 0, it should return -2.
IMPORTANT: This function might invalidate any data pointer returned by previous accessors. The accessor themselves remain valid, but any pointers returned by calls to value() / other functions might become invalid.
IMPORTANT 2: Users of this function should call emitMeshChanged() after changes to the mesh are completed. That allows for other objects that depend on mesh number of nodes and cell geometry to respond to the changes. The FEM assembler is an example of such object.

inlinevirtual |
Adds the set of cells in the given list to the cell group. Assumes that the intersection of the given list with the current group cells is empty.
This function should be reimplemented by mesh implementations that support the mesh cell group edition capability (hasCapability("editGroups") returns true).
Returns true on success. On error, this function should leave the mesh unchanged and return false.
|
inlinevirtual |
Adds the set of cells in the given list to the cell group.. The set of added cells is given by a vector with cell ranges. Each pair entry contains the cell index for the first and last cell in the range. Assumes that there is no intersection among the ranges and that the intersection of the given ranges with the current group cells is empty.
This function should be reimplemented by mesh implementations that support the mesh cell group edition capability (hasCapability("editGroups") returns true).
Returns true on success. On error, this function should leave the mesh unchanged and return false.
|
virtual |
Creates a new value set for storing data associated with the attribute whose metadata information was received as a parameter.
The new value set takes ownership of the info object. It should be noted that info MUST have kind equal to GM_CELL_ATTRIBUTE or GM_CELL_STATEVAR.
If this function is being called during mesh loading / initialization, the added attribute will only be available for value filling through an accessor after the call to initCellValueSets(), which should be made AFTER the mesh already knows its number of cells.
When called after attribute initialization, the new attribute will be imediately initialized with the correct size and will be ready for filling, unless the call is inside a beginAddingCellValueSets() / endAddingCellValueSets call block. In that later case, the new attribute size initialization is delayed untill the end call. This allows for the addition of several attributes to a new or existing "interleaved pack" in a much more efficient way.
The function returns false in case of errors (memory could not be allocated, or the mesh already has a cell attribute with the requested id, for example). In that case, info is NOT deallocated by addCellValueSet().

protectedvirtual |
Adds to 'state' accessors for all the cell attributes associated with this mesh. This includes all histories. (also adds node attributhe through the base class). Returns true on success or false on error.

pure virtual |
Returns a cell of the mesh.
IMPORTANT: The returned pointer can become invalid when new cells are added to the mesh. Please do NOT store cell pointers in any structure whose life span can include mesh changes.
| cellIndex | Cell identifier, from 0 to numCells() - 1 |

inlinevirtual |
Returns the maximum length of a cell bounding box diagonal in the mesh. The returned statistics are calculated on first usage and are not updated automatically when cell nodes change or have their coordinates updated. Use clearCellStatistics() to force an update.
|
inlinevirtual |
Returns the minimum length of a cell bounding box diagonal in the mesh. The returned statistics are calculated on first usage and are not updated automatically when cell nodes change or have their coordinates updated. Use clearCellStatistics() to force an update.
|
inlinevirtual |
Returns a list with the names of the available cell groups.
The order of group names in this list defines the value of group indices passed to the numCellsInGroup() and cellInGroup() functions. Support for cell groups is optional.
| const GmCellGroupSet * GmCellMesh::cellGroupSet | ( | const QList< int > & | groupIdList, |
| bool | disjoint ) |
Auxiliar function used to manage cell group sets attached to the mesh.
Given a cell group set definition (the indices of the cell groups belonging to the set and whether the groups are disjoint or not), returns the group set if it already exists or creates a new group set and returns the newly created group. Returns NULL if it was impossible to create the set.
If the id list is empty, a group set that represents the entire mesh will be returned.
|
inlinevirtual |
Returns a cell present in the group referenced by groupIndex.
The groupIndex parameter should be the index in the list returned by cellGroupIds() of the desired group. That means that if cellGroupIds() returns an empty list, this function should not be called at all. The cellIndex is a value between 0 and numCellsInGroup() - 1 defining the cell to be returned.
|
virtual |
Returns an accessor object for the property named by id.
If id does not reference a known property, returns NULL; Remember that there should be no intersection between property names of the several sets bound to a single mesh, so id specifies a unique property among the several possible property sets.
If desiredUnit is a known unit, different from the basic property unit, the value will be automatically converted to the desired unit. If no conversion is possible, the function returns NULL. To avoid conversions, just pass Unit() as the desiredUnit.
The logger parameter exists to allow for the accessor to use a different logger than the mesh one to report errors. For example, in an analysis context it might be interesting to report errors through the physics plugin logger instead of by the mesh logger.
IMPORTANT: The returned accessor should be deallocated by the caller.
|
virtual |
Returns the metadata of the property named by id.
If id does not reference a known property, returns NULL; Rememeber that there should be no intersection between property names of the several sets bound to a single mesh, so id specifies a unique property among the several possible property sets.
|
virtual |
Creates an accessor object for the state var associated with the requested degree of freedom number. Returns NULL if the dof number is invalid or if that cell state var is not associated with this mesh.
For state vars that store vector values, the state var can be recognized by any value in the range covered by its base dof and the next 'n-1' values where 'n' is the vector size.
If stateVar is different from NULL, returns the state var.
IMPORTANT: To recover an accessor for a state var with known id, it's much better to call cellValueAccessor(). This is not a fast function since there are no special indices to find a state var from its dof number (but that really should not be a problem unless you have hundreds of state vars or if you need to call this in a thight lopp, which you shouldn't any way).
If desiredUnit is a known unit, different from the basic cell value unit, the value will be automatically converted to the desired unit. If no conversion is possible, the function returns NULL. To avoid conversions, just pass Unit() as the desiredUnit.
IMPORTANT 2: The returned accessor should be deallocated by the caller.
|
virtual |
Overloads cellValueAccessor(QString, Unit, ...) to return an accessor for the requested previous state of a value.
The snum parameter contains the requested state. A value of zero means the current state, 1 the previous one, 2 the one before that and so on. Valid values range from zero to the oldest state for the requested variable, which can be queried with a call to numCellValueStates(). Remember that for a value accessor to support states, the history parameter must be set in its value info object.
The locked parameter controls the behaviour of the accessor once a new state is created for the value. The 'lock' refers to the state number, so if locked is false and a new state is created, the accessor doesn't change and continues to point to the same data. If locked is true, the accessor will be locked to that state number so when a new state is created, the accessor changes the data its looking upon to reflect the new satte. For example, an accessor locked on the state 0 will always point to the current state and one locked to the state 1 will always point to the previous saved value.
See the overloaded function for the remaining parameters.
|
virtual |
Creates an accessor object for the cell attribute named id.
If the id does not refer to a known attribute, returns NULL.
If desiredUnit is a known unit, different from the basic attribute unit, the value will be automatically converted to the desired unit. If no conversion is possible, the function returns NULL. To avoid conversions, just pass Unit() as the desiredUnit.
The logger parameter exists to allow for the accessor to use a different logger than the mesh one to report errors. For example, in an analysis context it might be interesting to report errors through the physics plugin logger instead of by the mesh logger.
IMPORTANT: The returned accessor should be deallocated by the caller.
Obs: This is equivalent to calling cellValueAccessor(id, 0, true, desiredUnit, logger)
|
virtual |
Returns the metadata describing the cell values (attribute / state var) associated with the named id.
Remember that cell attributes and state vars should have unique ids among themselves. If the id does not refer to a known attribute / state var, returns NULL.
If filter != -1, it should be one of GM_CELL_ATTRIBUTE or GM_CELL_STATEVAR and defines that the return value should be NULL if a matching value does not have the specified type.

Informs the mesh that the number of ghost nodes / total num nodes in a cell was updated to the given values, so that the mesh can update its statistics returned by maxNumCellGhostNodes() and maxTotalNumCellNodes().
This function should be reimplemented by mesh implementations that support ghost nodes (hasCapability("ghostNodes") returns true).
|
inlinevirtual |
Returns the maximum number of ghost nodes in a mesh cell.
This function should be reimplemented by mesh implementations that support ghost nodes (hasCapability("ghostNodes") returns true).
IMPORTANT: Depending on the concrete mesh implementation, this value might be an upper bound, reflecting that no cell has more than that number of ghost nodes, but without meaning that there is a cell with that number of ghost nodes. This allows for easier implementations for GmCell::removeGhostNode() without compromising the main usage of this function for allocating space big enough for all ghost nodes in a cell.
|
inlinevirtual |
Returns the maximum total number of nodes (normal + ghost) in a cell mesh.
This function should be reimplemented by mesh implementations that support ghost nodes (hasCapability("ghostNodes") returns true). Its value can be different from maxNumCellNodes() + maxNumCellGhostNodes() since the cell that contains the maximum number of ghost nodes might not have the maximum number of 'common' nodes.

Returns a const vector of size equal to GM_NUM_CELL_TYPES where each entry is the number of active cells of that type present in the mesh.
The first vector entry will be filled with the number of active cells present in the mesh with type equal to the first entry in the GmCellType enumeration. The second entry counts active cells of the second enumeration type and so on.

inlinevirtual |
Returns the number of cells present in the group referenced by groupIndex.
The groupIndex parameter should be the index in the list returned by cellGroupIds() of the desired group. That means that if cellGroupIds() returns an empty list, this function should not be called at all.

Returns the index in the list returned by propertySets() of the set that includes the named property.
If the id does not reference a known property, returns -1; Remember that there should be no intersection between property names of the several sets bound to a single mesh, so id specifies a unique property among the several possible property sets.
|
pure virtual |
Returns a reference to the list of property sets associated to this mesh.
The order of the property sets in the list must be consistent with results returned from propertySetIndex(), i.e, if a call to propertySetIndex("a") returns 1, the second entry of the list should be the property set that includes the "a" property.
|
virtual |
Saves the current state for the requested id, creating a new current state.
If the value does not supports history values, does nothing, returning false. The mode parameter defines how the new state will be initialized (with a copy of the old one, with the value default or uninitialized).
The time associated with the new current state is initialized to the value of the current time as seen from the simulation data object. This can later be changed by a call to setCellValueStateTime().
Returns true if the state was created successfully, false otherwise.

Simmilar to saveNodeValueState() / saveCellValueState(), saves the current state of all nodal and cell values that support state saving. See saveNodeValueState() / saveCellValueState() for more details.

If the mesh supports the topology capability (hasCapability("topology") returns true), returns the mesh topology object that should be used for such queries. If there is no support, returns NULL.
For the standard GeMA mesh plugin, the data structure supporting topological queries is only built on request. If the structure was not yet built, and create is false, the function will return NULL. If create is true, it will attempt to create the topological structure and return the associated object. If there was an error creating the structure, it will return NULL and log the error. The returned object should not be released by the user. Another way for creating the topological structure is by setting to true the topology flag on the mesh definition (for the GeMA mesh plugin)
THIS function should probably NOT be marked as const since it should build the topological structure if needed. Although we can interpret that as a kind of optimization and handle it
with mutable attributes, it is not pretty. We are keeping it as const since removing it causes problems with interpolator classes that would require a changes in several classes to solve.
