 FEA Software
LISA can be used for linear static, modal vibration, dynamic response, buckling, steady/transient heat flow, acoustic, steady fluid flow, DC current, electrostatics and magnetostatics. STEP, IGS, STL, CAD models can be automeshed. Mesh templates for pressure vessel components. The program is very easy to use and the extensively documented user manuals explains the how's and why's of everything fea in simple english. Easily the first choice for new entrants to FEA. 1300 node limit.

AutoFEM Lite Great choice for AutoCAD users moving into FEA, especially since there is no limitation on the maximum number of nodes. It does require you to have AutoCAD on your computer as it's an AutoCAD add-on. This is a lite version of their commerical product offering static, frequency, buckling & thermal analysis. As it is a free version, the following are the restrictions - only one solid object can be analysed at a time; for frequency analysis, only the first natural frequency is solved and for thermal analysis, only convection and fixed temperature boundary conditions can be applied.

UNA This is not a stand-alone FEA software, but is a solver that has to be used with other Pre/Post - processors such as FEMAP, PATRAN, I-DEAS, NASTRAN. The solver can be used for static analysis, modal analysis, elastic buckling, substructuring, transient response, frequency response, random vibrations, aeroelastic response. It is a sparse linear matrix solver, sparse Lancos eigenvalue solver. Automatically eliminates local singularities, etc.

IOSO NS Using IOSO NS, you can quickly and efficiently solve non-linear parametric optimization problem with dimensionality up to 5 independent variables and 5 functional inequality constraints. Family of IOSO NS versions utilizes set of heuristic self-organizing optimization algorithms. These algorithms are based on usage of owner-developed approximation technology. At every iteration of search for optimum response surfaces are being built for objective and constrained parameters, then these response surfaces are being optimized. Thus, the number of direct calls to mathematical model is minimized, and time expenditures for problem solution are also minimal. Using approximation technology makes it possible to solve successfully problems with complex topology of objective and constraints. Unlike the gradient methods, IOSO NS works robustly with discontinuous, non-differentiatable, noised and locally incomputable objectives and constraints.
