Flex-2D performs linear static analysis of plane truss structures using the Finite Element Method. It is general purpose in scope and easy to use. Solution of small to moderate size problems can be obtained. It was developed for use by design engineers civil structural and mechanical engineering students and experienced professionals who desire rapid and accurate solutions to a wide variety of problems.

The model creation process includes adding materials nodes trusses restraints loads and optionally springs to define the structure. The system of linear equations is solved and results can be viewed in a text file or plotted. Displacements forces and stresses can be displayed.

Templates are available for rapid creation of common truss structures such as bridges and roofs. Sample models of various structure types are also included.
