Base interface for FEM (finite element) meshes.
This interface basically adds methods related to FEM models.
|
virtual |
Creates a new value set for storing data associated with the Gauss attribute whose metadata information was received as a parameter.
The new value set takes ownership of the info object. After this function returns, attribute values can be added to the new value set through an accessor.
It should be noted that info MUST have kind equal to GM_GAUSS_ATTRIBUTE and that this function should be called AFTER the mesh already knows its number AND TYPE of cells (since both are needed while creating a ValueSet).
The function returns false in case of errors (memory could not be allocated, or the mesh already has a Gauss attribute with the requested id, for example).
In that case, info is NOT deallocated by addGaussAttributeSet().
This function calls createGaussValueSet() to actually instance the value set object, allowing for derived classes to work with other kinds of value sets derived from GmGaussValueSet. This is particulary important for the XFem plugin.
| const GmBorderIntegrationRule * GmElementMesh::borderIntegrationRule | ( | GmCellType | type, |
| int | ruleSet, | ||
| int | borderIndex | ||
| ) | const |
Returns the integration rule associated with a border (face for 3D elements or edge for 2D elements) of the received element type / rule set.
For 2D elements it is equivalent to edgeIntegrationRule() and for 3D elements to faceIntegrationRule(). This function is undefined for line elements. It can be used for building generic code that works for both 2D and 3D elements.
The border index parameter is used only if type is a 3D element with more than one face type (like a wedge). In that case, it should be the face index for the integration face and will be used to choose the correct face rule to be used. Otherwise, any valid face / edge index can be used (like 0).
| const GmBorderIntegrationRule * GmElementMesh::faceIntegrationRule | ( | GmCellType | type, |
| int | ruleSet, | ||
| int | faceIndex | ||
| ) | const |
Returns the integration rule associated with an element face of the received element type / rule set. This function is undefined for line or 2D elements.
The face index parameter is used only if type has more than one face type (like a wedge). In that case, it should be the face index for the integration face and will be used to choose the correct face rule to be used. Otherwise, any valid face index can be used (like 0).
|
virtual |
Creates an accessor object for the Gauss 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 gaussAttributeAccessor(id, 0, true, desiredUnit, logger)
|
virtual |
Overloads gaussAttributeAccessor(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 numGaussAttributeStates(). 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 |
Returns the metadata describing the Gauss attribute named id.
If the id does not refer to a known attribute, returns NULL.
| GmMeshGaussIndex * GmElementMesh::gaussIndex | ( | int | ruleSet | ) | const |
Returns the index object associated with the given rule set. The index is created on the first call to this function for the given rule set. Returns NULL if the index could not be created.
The implementation uses the DCL pattern. See comments on getIntegrationRuleWithDCL() for additional information.
|
protected |
Auxiliar function that uses the Double Checked Locking Pattern (DCLP) to grab an integration rule from the given list, creating it by calling instance() if the list doesn't already have an integration rule for the given type and rule set.
Using DCLP guranteees that all accesses but the first one have minimum overhead.
See https://preshing.com/20130930/double-checked-locking-is-fixed-in-cpp11/ for an extensive documentation about the DCLP problem.
The faceType parameter should be passed as 0 for non face lists.
|
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 setGaussAttributeStateTime().
Returns true if the state was created successfully, false otherwise.
| bool GmElementMesh::setElementIntegrationRule | ( | GmCellType | type, |
| GmIntegrationRule * | rule, | ||
| int | ruleSet | ||
| ) |
Allows the user to exchange the default integration rule tied to an element type / rule set.
Integration rules are tied to element types and not to elements in order to allow the element to be a lightweight object. Since in most scenarios all elements of a type will share an integration rule, we really don't need to store a pointer to an integration rule in each and every element.
Returns false if the rule is not compatible with the element type. Otherwise, returns true and takes the ownership of the integration rule that will be deleted by the mesh destructor.
Obs: If the per element type (and rule set) schema proves to be too stringent and we really need to have two elements of the same type, in the same rule set, with different integration rules a not so complicated solution would be to implement the concept of subtypes, associating rules with subtypes and not types anymore. Each type can have a (fixed) number of subtypes. This can be implemented rather efficiently if we use, for example 2 bits from element id numbers to store the subtype (which would give 4 subtypes and still let us have a mesh with 1G elements).
| bool GmElementMesh::setFaceIntegrationRule | ( | GmCellType | type, |
| GmBorderIntegrationRule * | rule, | ||
| int | ruleSet, | ||
| int | faceType | ||
| ) |
Allows the user to exchange the default integration rule tied to a face of an element type. Please, see additional comments on setElementIntegrationRule()
The faceType parameter is used when the element type has faces with different types (wedge, for example). In this case, one different rule should be stored for each face type. For elements with a single face type, this parameter must be filled with the element's face type or with -1 (the type will be inferred from the element type).
