Information in wikipedia format Use the wayback machine for old versions of http://www.tochnogprofessional.nl . Tochnog Professional is a free Finite Element program, both for academic and commercial use. It offers a wide variety of geotechnical, civil and mechanical options; modern material laws including the most recent rate independent and viscous hypoplasticity models; stress, temperature and groundwater pressure analysis; lagrangian and eulerian mesh in space; quasi-static and dynamic calculations. Linux and Microsoft Windows. Parallel computations. Dedicated pre- and postprocessing interfaces. A full libary of isoparametric elements in 1D, 2D and 3D and also typical structural elements like beams, interfaces, springs, etc.; geometry based boundary conditions; mesh independent postprocessing by selecting physical points, lines and surfaces; 2D and 3D mesh refinement; phased modelling stages.
