class | TestStressRecoveror |
Finite elasticity solver. Solves static *compressible* nonlinear elasticity problems with arbitrary (compressible) material laws and a body force.
Uses quadratic basis functions for displacement, and is therefore outside the other assembler or solver hierarchy.

Assemble residual or Jacobian on an element, using the current solution stored in mCurrrentSolution. The ordering assumed is (in 2d) rBElem = [u0 v0 u1 v1 .. u5 v5].
rElement | The element to assemble on. |
rAElem | The element's contribution to the LHS matrix is returned in this n by n matrix, where n is the no. of nodes in this element. There is no need to zero this matrix before calling. |
rAElemPrecond | The element's contribution to the matrix passed to PetSC in creating a preconditioner |
rBElem | The element's contribution to the RHS vector is returned in this vector of length n, the no. of nodes in this element. There is no need to zero this vector before calling. |
assembleResidual | A bool stating whether to assemble the residual vector. |
assembleJacobian | A bool stating whether to assemble the Jacobian matrix. |
