    Calculix Alternatives

    Calculix is described as 'free and open-source finite-element analysis application that uses an input format similar to Abaqus. It has an implicit and explicit solver written by Guido Dhondt and a pre- and post-processor written by Klaus Wittig' and is an app. There are eight alternatives to Calculix for Windows, Linux, Mac, GNU Octave and MATLAB. The best alternative is Elmer, which is both free and Open Source. Other great apps like Calculix are COMSOL Multiphysics, KRATOS Multiphysics, FEATool Multiphysics and Code_Aster for Windows.
