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.

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

template<unsigned DIM>

CompressibilityType SolidMechanicsProblemDefinition< DIM >::GetCompressibilityType ( )

Returns: 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 )

Returns: 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 )

Returns: 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

template<unsigned DIM>

bool SolidMechanicsProblemDefinition< DIM >::GetSolveUsingSnes ( )

Returns: whether solver should use PETSc SNES nonlinear solver or not

template<unsigned DIM>

bool SolidMechanicsProblemDefinition< DIM >::IsHomogeneousMaterial ( )

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

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,
		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

Definition at line 83 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
