Open Source Cygwin CAD Software

PSA(Program for Structural Analysis) is able to analyse Framed structures using FEM(Direct Stiffness Method). Apart from giving the analysed results, PSA is able to give user the various stiffness Matrices generated during the analysis, as web page.

ParaFEM is an open source platform for parallel finite element analysis. The source code and philosophy are documented in the text book Smith, Griffiths and Margetts, "Programming the Finite Element Method", 5th Edition, Wiley, 2014. The software is written in modern Fortran and uses MPI for message passing.

CalculiX Binaries for MS Windows, made with CYGWIN and ARPACK libraries. CalculiX is most popular FEA open-source package (like Code-Aster and Elmer-FEM). it is comparable in features with most known commercial packages like ANSYS, NASTRAN, Abaqus, etc. Good for structural, mechanical, thermal and fluid applications (trusses, plates, frames, shells, solid bodies). It has powerful nonlinear capabilities (including tension/compression only material like concrete) and most types of analysis (modal, thermal, buckling, coupled, etc) .
