SIMULIA is a CAE suite built on the 3DEXPERIENCE® platform by Dassault Systèmes and used to create realistic simulations.
SIMULIA tools deliver various types of computational simulations (electromagnetic, computer fluid dynamic, multibody dynamic analysis, structural analysis) and capabilities to increase their efficiency (standard processes automation, logical and physical models integration, collaboration and sharing).
FreeCAD is a customizable, open-source paramentic 3D CAD and BIM software with FEM support, built on the Opencascade geometric kernel. It was created primarily for product design and mechanical engineering, but it can be used in a wide range of industries, such as electrical engineering, or architecture. It runs on Windows, Mac OS, and Linux.
FreeCAD is made to craft real-life objects of different sizes and is perfect for a home user/amateur, programmer, experienced CAD software user, or educator. This software provides tools similar to those of SolidWorks, Catia or Autodesk Revit.
