LUSAS Finite Element System 19.0

LUSAS Finite Element System is a comprehensive finite element analysis suite used across civil, structural, bridge, geotechnical, and general engineering. It combines flexible pre- and post-processing with robust solvers to handle linear and nonlinear behavior, static and dynamic loading, thermal effects, buckling, vibration, contact, and staged construction. Industry-focused options support bridges, buildings, and advanced materials such as composites, enabling accurate modeling of material and geometric nonlinearity, large deformations, and soil–structure interaction. Efficient meshing tools and CAD interoperability streamline model creation, while clear visualization—contours, vectors, sections, and animations—helps engineers interpret results and communicate findings. From concept through detailed design, LUSAS helps assess performance, improve safety and serviceability, and optimize designs for projects ranging from individual components to large-scale infrastructure.

LUSAS Finite Element System is developed by Finite Element Analysis Ltd.. The most popular version of this product among our users is 19.0. The name of the program executable file is Lusas_M.exe.
