Constructors

TPZLinearAnalysis()

Create an empty TPZLinearAnalysis object.

TPZLinearAnalysis(TPZCompMesh *mesh, bool mustOptimizeBandwidth = true, std::ostream &out = std::cout)

Create an TPZLinearAnalysis object from one mesh pointer.

TPZLinearAnalysis(TPZAutoPointer<TPZCompMesh> mesh, bool mustOptimizeBandwidth = true, std::ostream &out = std::cout)

Create an TPZLinearAnalysis object from one mesh auto pointer object.

FEM

template<class TVar>
TPZMatrixSolver<TVar> &MatrixSolver()

Get the matrix solver.

inline TPZSolutionMatrix &Rhs()

Returns the load vector.

virtual void Assemble() override

Assemble the stiffness matrix and load vector.

virtual void AssembleResidual()

Assemble the load vector.

virtual void Solve() override

Invert the stiffness matrix.

virtual void SetSolver(const TPZSolver &solver) override
