OFELI (Object Finite Element LIbrary) is a library of finite element C++ classes for multipurpose development of finite element software. It is intended for teaching, research and industrial developments as well.

The TFEL library is a collaborative effort of the French Atomic Commission and Électricité de France. TFEL mostly includes the MFront code generator. MFront is based on C++ and provides several domain specific languages which were designed to simplify the implementations of new material properties, mechanical behaviours and simple material models. A particular focus was made on mechanical behaviours which are by essence more complex and may have significant impact on the numerical performances of mechanical simulations. Various performance benchmarks show that the code generated using MFront is in most cases on par or better than other implementations, generally written in Fortran. For mechanical behaviours, MFront introduces interfaces for various finite element or FTT solvers (Cast3M, Code-Aster, ZeBuLoN, Abaqus, Europlexus, AMITEX_FFT, etc..). The authors hope that it will prove usefull for researchers and engineers, in particular in the field of solid mechanics.

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.

INMS provides an easy to use interface to calculate basic parameters in drip irrigation in Tunisia. it uses FAO's CLIMWAT database to extract ETP values in Tunisian climate stations.

IBAP is a structural beam analysis software that can be used by Civil, Mechanical and Structural Engineers, Beam designers and Engineering students for both professional and academic purposes.

YAFEMS (Yet Another Finite Element Method Solver) is a FEM solver for Linux and WIndows that reads a MED mesh file produced by Salome (http://www.salome-platform.org/) with certain groups created into the mesh, and with the help of an input text file (.yaf), performs a 3D or 2D plane stress or plane strain analysis and creates results in plain text format and in MED format. This way a complete analysis can be carried inside Salome, where a mesh file can be created, exported and read by YAFEMS with the help of a .yaf input file and post-processed within Salome using ParaView. New in v0.4 - More performance boost due to the implementation of the Cuthill-McKee algorithm.
