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
compressibilityTypecompressibility type
pMaterialLawmaterial 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
elementIndexindex 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
elementIndexindex of element

template<unsigned DIM>
bool SolidMechanicsProblemDefinition< DIM >::GetSolveUsingSnes ( )
inline
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
rFixedNodesthe fixed node indices
rFixedNodeLocationcorresponding 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
compressibilityTypeeither 'INCOMPRESSIBLE' or 'COMPRESSIBLE'
pMaterialLawThe 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
compressibilityTypeeither 'INCOMPRESSIBLE' or 'COMPRESSIBLE'
rMaterialLawsVector of pointers to material laws

Definition at line 110 of file SolidMechanicsProblemDefinition.cpp.

template<unsigned DIM>
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
solveUsingSnessolve using Snes or not

template<unsigned DIM>
void SolidMechanicsProblemDefinition< DIM >::Validate ( )

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

Member Data Documentation

template<unsigned DIM>
CompressibilityType SolidMechanicsProblemDefinition< DIM >::mCompressibilityType

std::vector<AbstractCompressibleMaterialLaw<DIM>*> SolidMechanicsProblemDefinition< DIM >::mCompressibleMaterialLaws
private

The material law, in the case of compressible material laws. This vector is either of size 1, representing a homogeneous material, or of size num_elements, representing a heterogeneous material, with a material law per element. If the material is incompressible, this vector will be of size zero.
