We are experts in using the Abaqus FEA product suite from Dassault Systèmes. We believe that Abaqus is the industry leader in advanced nonlinear FEA. Abaqus FEA product suite includes Abaqus/CAE wich is a powerful pre- and post-processing user interface. There are three tightly integrated solvers in Abaqus:

Abaqus/Standard: Implicit solutions and a range of contact and nonlinear material options for static, dynamics, thermal, and multiphysics analyses.

Abaqus/Explicit: high-speed, nonlinear, transient response and multiphysics applications.

Abaqus/CFD: This is a relatively new solver for Computational Fluid Dynamics which can be useful for performing fluid-structure interaction (FSI) analysis all within Abaqus.
