Our Applications

Libra Finite Element Analysis Program
Libra is an efficient, general-purpose, finite element method program applicable to static, dynamic and heat transfer analyses of structural systems. The program contains a comprehensive library, and over twenty solution algoritms taking advantage of both Gaussian and iterative solvers. In addition the program has a fully integrated editor for model generation, and comprehensive post-processing and plotting capabilities. Libra can execute problems of over 250,000 degrees of freedom on computers configured with 256 MB of available memory and 20 GB of hard drive. Libra 10 is now 64-bit compatible.
