Detailed Description
template<typename Scalar>
class Hermes::Hermes2D::LinearSolver< Scalar >
Class for solving linear problems.
Typical usage:
// Initialize linear solver.
// Here wf is Hermes2D::WeakForm<double>, space is Hermes2D::Space<double>
Hermes::Hermes2D::LinearSolver<double> linear_solver(&wf, &space);
// Solve the linear problem.
try
{
// Just call solve().
linear_solver.solve();
// Get the solution vector from the solver.
double* sln_vector = linear_solver.get_sln_vector();
// Translate the solution vector into the previously initialized Solution<double> using the static method vector_to_solution.
Hermes::Hermes2D::Solution<double>::vector_to_solution(sln_vector, &space, &sln);
}
// All kinds of Exceptions may happen (Linear algebraic solver, some bad parameters, some data not initialized...)
catch(Hermes::Exceptions::Exception& e)
{
e.print_msg();
return -1;
}
// For illustrative purposes, otherwise one can just catch std::exception directly, as Hermes::Exceptions::Exception derive from it.
catch(std::exception& e)
{
std::cout << e.what();
return -1;
}
