Detailed Description

template<unsigned DIM, bool CAN_ASSEMBLE_VECTOR, bool CAN_ASSEMBLE_MATRIX>
class AbstractContinuumMechanicsAssembler< DIM, CAN_ASSEMBLE_VECTOR, CAN_ASSEMBLE_MATRIX >

Abstract class for assembling volume-integral parts of matrices and vectors in continuum mechanics problems.

For such problems, the matrix has, essentially, the form [A B1] [B2^T C ] (where often B1=B2 and C=0) and the vector has the form [b1] [b2] A is the spatial-spatial part, B1 the spatial-pressure part, etc.

Currently B1=B2 is assumed, this can be changed in the future.

This class works in the same way as the volume assembler in pde (AbstractFeVolumeIntegralAssembler), except the concrete class has to provide up to 6 methods, for each of the blocks A,B1,B2 and for b1 and b2.

The assembler is main used for fluids - currently it is used for assembling the matrix for Stokes flow [A B ; B^T 0], and the preconditioner for Stokes flow [A, B; B^T M], and will be useful for further fluids assemblies, and could be used for mixed-problem incompressible linear elasticity. We DON'T use this assembler in the incompressible nonlinear elasticity solver, because even though the matrix is of the right form, things like stress and stress-derivative need to be computed at the AssembleOnElement level and the assembly is in general too complex for this class to be used.

NOTE: The elemental matrix and vector is as above. The full matrix and vector uses a completely different ordering: for parallelisation reasons the pressure variables are interleaved with the spatial variables and dummy pressure variables are used for internal nodes. For example, in 2d, the ordering is [U1 V1 P1 , .. , Un Vn, Pn] where n is the total number of nodes.

For a continuum mechanics problem in mixed form (displacement-pressure or velocity-pressure), the matrix has the form (except see comments about ordering above) [A B1] [B2^T C ] (where often B1=B2 and C=0). The function is related to the pressure-pressure block, ie matrix C.

For the contribution to A from a given element, this method should return the INTEGRAND in the definition of C. See concrete classes for examples. Needed to be implemented (overridden) if the concrete class is going to assemble matrices (ie if CAN_ASSEMBLE_MATRIX is true).

Default implementation returns a zero matrix - ie the block will be zero if this is not over-ridden

Parameters

rLinearPhi	All the linear basis functions on this element, evaluated at the current quad point
rGradLinearPhi	Gradients of all the linear basis functions on this element, evaluated at the current quad point
rX	Current location (physical position)

Returns
