...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.

This library contains several of user material subroutines for implicit quasi-static (UMAT) and explicit dynamic (VUMAT) versions of the Abaqus solver. The project web site: http://abumpack.sf.net. The Abaqus is a proprietary finite element (FE) code ( http://www.3ds.com/products-services/simulia/products/abaqus/). Users can write subroutines for use with the Abaqus. Linear elastic, isotropic hardening plasticity, Gurson-Tvergaard-Needleman (GTN), Rousselier constitutive models are provided. ...

A collection of Fortran 2003, 90 and 77 routines, modules and programs for automatic simulation based global constrained optimisation. The initial application is for FE simulation of elasto-plastic buckling of steel rods aimed at tuning the hardening model. Unix shell scripts are used extensively. High concurrency is achieved with parallel multi-start global search and with parallel MPI FE. Powell's BOBYQA or LINCOA are used (not included in this package). Automatic mesh generation of 3D...
