Detailed Description

template<unsigned DIM>
class SolidMechanicsProblemDefinition< DIM >

A class for specifying various parts of a solid mechanics problem, in particular the material laws for the deforming body, and (inheriting functionality from a base class): fixed nodes information, the body force (per unit mass) (usually acceleration due to gravity or zero), the traction boundary conditions, and the density.

template<unsigned DIM>

void SolidMechanicsProblemDefinition< DIM >::CheckCastSuccess	(	CompressibilityType	compressibilityType,
		AbstractMaterialLaw< DIM > *	pMaterialLaw
	)		`[private]`

Helper function for checking whether a dynamic_cast succeeded or not, and throwing an exception if it failed.

Parameters:

compressibilityType	compressibility type
pMaterialLaw	material law

References EXCEPTION.

template<unsigned DIM>

CompressibilityType SolidMechanicsProblemDefinition< DIM >::GetCompressibilityType ( )

Get whether the material is incompressible or compressible. SetMaterialLaw() must be called before calling this. (Which can be checked by calling Validate()).

template<unsigned DIM>

AbstractCompressibleMaterialLaw< DIM > * SolidMechanicsProblemDefinition< DIM >::GetCompressibleMaterialLaw ( unsigned elementIndex )

Get the material law for a given element, when the body is compressible. An assertion will fail if GetCompressibilityType()!=COMPRESSIBLE. If the material is homogeneous, it doesn't matter what the element index is.

Parameters:

elementIndex index of element

Definition at line 184 of file SolidMechanicsProblemDefinition.cpp.

template<unsigned DIM>

AbstractIncompressibleMaterialLaw< DIM > * SolidMechanicsProblemDefinition< DIM >::GetIncompressibleMaterialLaw ( unsigned elementIndex )

Get the material law for a given element, when the body is incompressible. An assertion will fail if GetCompressibilityType()!=INCOMPRESSIBLE. If the material is homogeneous, it doesn't matter what the element index is.

Parameters:

elementIndex index of element

bool SolidMechanicsProblemDefinition< DIM >::GetSolveUsingSnes ( ) [inline]

Get whether solver should use Petsc SNES nonlinear solver or not

Definition at line 195 of file SolidMechanicsProblemDefinition.hpp.

template<unsigned DIM>

bool SolidMechanicsProblemDefinition< DIM >::IsHomogeneousMaterial ( )

Get whether the material is homogeneous or heterogeneous. SetMaterialLaw() must be called before calling this.

Definition at line 147 of file SolidMechanicsProblemDefinition.cpp.

template<unsigned DIM>

void SolidMechanicsProblemDefinition< DIM >::SetFixedNodes	(	std::vector< unsigned > &	rFixedNodes,
		std::vector< c_vector< double, DIM > > &	rFixedNodeLocation
	)

Set a list of nodes to be fixed, with their corresponding new LOCATIONS (not displacements). (This class will store as displacements though, and it is displacements that will be returned by rGetDirichletNodeValues).

Parameters:

rFixedNodes	the fixed node indices
rFixedNodeLocation	corresponding locations

Definition at line 52 of file SolidMechanicsProblemDefinition.cpp.

template<unsigned DIM>

void SolidMechanicsProblemDefinition< DIM >::SetMaterialLaw	(	CompressibilityType	compressibilityType,
		std::vector< AbstractMaterialLaw< DIM > * > &	rMaterialLaws
	)

Set a vector of material laws for the body, one for each element in the mesh (the heterogeneous case). If compressibilityType==INCOMPRESSIBLE, the material law pointer will be checked at run-time that it is of type `AbstractIncompressibleMaterialLaw`, and similarly for the compressible case. Any previous material information will be deleted.

Parameters:

compressibilityType	either 'INCOMPRESSIBLE' or 'COMPRESSIBLE'
rMaterialLaws	Vector of pointers to material laws

Definition at line 110 of file SolidMechanicsProblemDefinition.cpp.

template<unsigned DIM>

void SolidMechanicsProblemDefinition< DIM >::SetMaterialLaw	(	CompressibilityType	compressibilityType,
		AbstractMaterialLaw< DIM > *	pMaterialLaw
	)

Set a material law for the entire body (ie the homogeneous case). If compressibilityType==INCOMPRESSIBLE, the material law pointer will be checked at run-time that it is of type `AbstractIncompressibleMaterialLaw`, and similarly for the compressible case. Any previous material information will be deleted.

Parameters:

compressibilityType	either 'INCOMPRESSIBLE' or 'COMPRESSIBLE'
pMaterialLaw	The material law for the entire body

void SolidMechanicsProblemDefinition< DIM >::SetSolveUsingSnes ( bool solveUsingSnes = true ) [inline]

Tell the solver class whether to use the PETSc SNES solver (the petsc nonlinear solver) or its own nonlinear solve implementation.

Parameters:

solveUsingSnes solve using Snes or not

void SolidMechanicsProblemDefinition< DIM >::Validate ( ) [virtual]

Check all variables are set appropriately. Exceptions are thrown if any are not. Derived classes can override but should call this version as well.
