A number of packages for general finite element analysis (FEA) have been developed for linear and nonlinear structural analysis, fluid flow, solid-fluid interaction, heat conduction, flow through porous media, and coupled physical problems.
The solvers are supported by the original graphical pre- and post-processors and can be coupled with generally adopted software which designs and generates finite elements for input data and output results.
Its basic development dates back several decades and is based on fundamental research conducted at the University of Kragujevac in collaboration with world renowned institutions such as M.I.T., the Technical University of Athens, the Imperial College, Harvard University, etc., and in conjunction with industry.
ITC Software offers the packages as software solutions for specific applications and offers services for advanced numerical analyses and simulations.
