NEi Nastran is a general purpose finite element analysis tool which is used to analyze linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components. It represents the latest in FEA technology with accurate solutions that have been trusted for over 15 years by companies in all industries.

Femap is a pre- and post-processor used by engineering organizations worldwide to model various products, processes, and systems. Its graphical user interface provides streamlined, direct access to all Femap® functionality. The pre- and post-processor is tightly integrated with NEi®Nastran and also provides integration to a wide range of industry-standard structural and thermal solvers.

Multiframe is a suite of structural analysis and design software that works the way structural engineers do.
It has been developed from the ground up for the Windows environment providing you with familiar techniques for building and analysing structural models and smoothly exchanging data with Excel, AutoCad and other Windows programs.

Multiframe provides linear and non-linear analysis, static and dynamic options and buckling calculations. These analysis options are complemented by a full range of analysis-related modelling tools like master-slave, prescribed displacements, springs, thermal effects, offset members, additional masses and much more. But Multiframe doesn't stop with the analysis. Other modules allow you to draw section shapes and install them in the sections library and perform design checks for a range of design codes.

LS-DYNA is an advanced general-purpose multiphysics simulation software package that is actively developed by the Livermore Software Technology Corporation (LSTC). While the package continues to contain more and more possibilities for the calculation of many complex, real world problems, its origins and core-competency lie in highly nonlinear transient dynamic finite element analysis (FEA) using explicit time integration. LS-DYNA is being used by the automobile, aerospace, construction, military, manufacturing, and bioengineering industries.
