GetDP 2.4.3

An Open Source general finite element solver for Linux that uses mixed elements.
GetDP is an open source and totally free general environment for the treatment of discrete problems using mixed elements to discretize de Rham-type complexes in 1, 2, and 3 dimensions.

GetDP features closeness between the input data, which defines discrete problems and the symbolic mathematical expressions of these problems.

The following example will give you an idea on how to solve the Poisson equation div(a grad(v)) = f on a domain D, using an input file (".pro" file):

 FunctionSpace {
 { Name H1; Type Form0;
 BasisFunction {
 { Name sn; NameOfCoef vn; Function BF_Node; Support D; Entity NodesOf[All]; }
 }
 }
 }
 Formulation{
 { Name Poisson; Type FemEquation;
 Quantity {
 { Name v; Type Local; NameOfSpace H1; }
 }
 Equation {
 Galerkin { [ a[] * Dof{d v}, {d v} ] ; In D; Jacobian V; Integration I; }
 Galerkin { [ f[], {v} ] ; In D; Jacobian V; Integration I; }
 }
 }
 }
