![]() ![]() The system of bricks, now mature, is used to assemble components such as standard models (elasticity in small and large deformations, Helmholtz problem, scalar elliptic problem. GetFEM++ offers a description of models in the form of bricks whose objective is to enable reusability of the approximations made. The dimension of the problem is arbitrary and may be a parameter of the problem. GetFEM++ is basically a generic C++ finite element library which aims to offer the widest range of finite element methods and elementary matrix computations for the approximation of linear or non-linear problems, possibly in hybrid form and possibly coupled. The following figure presents a 3D bridge before optimization. The following figure presents the same bridge after optimization. The following figure presents a 2D bridge before optimization. rank_efficient_struct : Test the validity of a stiffness matrix.plotsection : Plot the sections of a truss structure.plotdeforme : Plot a deformed truss structure. ![]() localise3d : Returns the position in the matrix of a given point (3D).localise2d : Returns the position in the matrix of a given point (2D).femtruss : Computes the deformation of a truss structure.femmode : Computes the modes of a structure.dfemtruss_smw : Compute the partial derivative of the nodal displacements.dfemtruss_ana : Compute the analytical partial derivative of the nodal displacements.build_fem_test : Create some test structures in 2 or 3 dimensions.The following is the list of functions in this module : In the demos directory, you will find some demos related to structural optimization, computation of partial derivatives and display of structures. It has been created by Yann Collette in 2009-2010 and is maintained as an open-source project under GPL on : The Femtruss module is a a Truss finite element code for scilab: the connection between SAMCEF® and Scilab.The goal of this page is to present the finite element tools which are available in the Scilab environment.
