FreeCad free software for creating parametric 3d models CAD

 It is completely free software for creating 3d models.  It has a parameterization function that greatly reduces the time needed to work on a model or a widely understood structure.

Free CAE software CALCULIX

  CAE programs based on the finite element method are an important tool for every designer and FEA engineer.  Most of the implementation departments (RnD) of companies producing high-tech devices / machines have CAE-type engineering support software. However, it often happens that due to the price of commercial programs using the finite element method, companies simply cannot afford such tools to increase design efficiency. Therefore, the appropriate alternative are CAE programs of the OPEN SOURCE type, thanks to which companies with less financial potential are able to compete with hegemons in the markets.

SALOME MECA open source software for FEA / CAE analysis

 Another very complex program that uses the finite element method is Salome Meca (Code Aster).The Code Aster program has been developed by EDF since 1989.It is quite a little popular software (OPEN SOURCE type) but worth attention. In this post, I will explain the specifics of this type of solution a little more.

ParaView - open source postporcessing software for data analysis

 In many studies, appearance is the factor that attracts attention. During the face to face presentation, 90% of the speaker's perception is assessed by appearance and gestures (according to the latest research).
