Member Function Documentation

◆ addStateItemsToGroup()

bool GmpFemNLSolver::addStateItemsToGroup	(	GmStateDump *	state,
		int	groupId
	)

protectedvirtual

Adds to 'state' the data items that should be saved for this FEM process. Should probably be overriden by derived classes to add their own requirements.

Auxiliar variant map dump item that notifies us for loading and saving data to the map

< Our "father" solver object

Reimplemented from GmpFemSolver.

◆ applyFixedBoundaryConditions()

bool GmpFemNLSolver::applyFixedBoundaryConditions ( int * numFixed )

protectedvirtual

Apply Dirichlet (fixed) boundary conditions to the global equation system.

Apply boundary conditions, clearing rows and columns in the stiffness matrix and adjusting the global force vector as needed.

Follows the procedures described by Fellipa in sections 3.6.1 and 3.6.2 (pages 3-12 and 3-13). Our algorithm does the same thing as the one presented in figure 21.5 (page 21-7), but in a different way (hopefully more clear).

Returns in numFixed the number of degrees of freedom "removed" from the system.

Reimplemented from GmpFemSolver.

◆ fillStiffnessMatrixBFGS()

GmpFemPhysics::FemResultType GmpFemNLSolver::fillStiffnessMatrixBFGS ( )

protectedvirtual

Evaluates the stiffness matrix using BFGS method.

Evaluates stiffness matrix and internal forces using BFGS method.

GmpFemPhysics::FemResultType GmpFemNLSolver::fillStiffnessMatrixBroyden ( )

protectedvirtual

Evaluates the stiffness matrix using Broyden's method.

Evaluates stiffness matrix and internal forces using Broyden's method.

◆ init()

bool GmpFemNLSolver::init ( )

virtual

Prepares the solver for assembling matrices by creating the assembler object and allocating the needed memory. This operations only need to be done once if the solver is used in a loop.

When overriding this function, if you need to pass to the assmebler different configurations from the default (REMOVE_DOF & false), consider calling initSolver() in your reimplementation instead of init().

Reimplemented from GmpFemSolver.

◆ initElementSets()

bool GmpFemNLSolver::initElementSets ( GmNumSolver * solver )

protectedvirtual

Helpper function used to initialize the matrix / vector sets with the definition of the needed types and also the relationships of those sets with the assembler.

In a nutshell, this function is responsible for callint the initTypes() methods from matrix and vector sets. It is also its responsibility to call other configuration functions such as GmpFemMatrixSet::setTransposedDofVector(), GmpFemVectorSet::addTransposedDofVector() and GmpFemVectorSet::addSavedDofVector() as needed to drive the method that will be used by the assembler.

This is the function to be reimplemented when a different solver driver needs to ask elements for additional matrices / vectors.

Returns false on errors.

Reimplemented from GmpFemSolver.

◆ iterativeSolver()

bool GmpFemNLSolver::iterativeSolver	(	double	dt,
		double *	newt,
