Tochnog Professional – Free FEM Code
[Official Distributor Text]
Tochnog Professional is a Finite Element program offering a wide variety of geotechnical 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; a full libary of isoparametric elements in 1D, 2D and 3D and also featuring 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 and extensive parallelisation. Tochnog accepts user defined models in ABAQUS UMAT format.
Tochnog Professional Company only provides support when you pay for a support contract. Without such contract, you need to help yourself with the manuals and example files. See also http://www.tochnogprofessional.nl/support/page.php.
