Precise Simulation describes FEATool as “a complete and self-contained toolbox featuring a full suite of functions and subroutines for preprocessing, grid generation, FEM (finite element model) assembly, solvers, post-processing and visualization.” You can combine the software's predefined physics modes for multiphysics simulation problems such as fluid flow, heat transfer, structural stresses, electrostatics, reaction and transport of mass and chemical species, says the company. Users can modify physics mode equations as well as specify their own equations.

Features include one-, two- and three-dimensional geometry modeling with linear, triangular/tetrahedral and quadrilateral/hexahedral cells as well as automatic grid generation support for complex geometries with triangular cells. FEATool offers a finite element library that includes constant, first and second order conforming and non-conforming FEM shape functions. Customized FEM shape functions are supported.

FEATool Multiphysics enables users to set up stationary and time-dependent computational fluid dynamics (CFD) simulation problems inside of MATLAB and Octave. Shown here is a CFD simulation of vortex shedding. Image courtesy of Precise Simulation Ltd.

Version 1.4 of FEATool sees improvements in its ability to import, export and convert data with the Feat(Flow) flow solvers, the GiD pre- and post-processor, the GMV (General Mesh Viewer) 3D scientific visualization tool, the Gmsh 3D finite element mesh generator and the
