Detailed Description

template<typename T_MATRIX, typename C_MATRIX, typename VECTOR>
class getfem::model_state< T_MATRIX, C_MATRIX, VECTOR >

Model State : contains all storage needed by the bricks (.

See also:

mdbrick_abstract)

The model state is

• a tangent matrix (the linear system that is solved)
• a constraints matrix (the Dirichlet conditions etc.), and its right hand side.
  • a state (the solution of the linear system)
  • a residual (residual_ = A*x - B)
  • the same information, reduced (i.e. after removal of constraints).
