It is an Open Source FEA project. The solver uses a partially compatible ABAQUS file format. The pre/post-processor generates input data for many FEA and CFD applications: Guido Dhondt, Klaus Wittig: 2.20: 2022-08-01: GNU GPL: Free: Linux, Windows: DIANA FEA
Abaqus FEA [4] [5] (formerly ABAQUS) is a software suite for finite element analysis and computer-aided engineering, originally released in 1978. The name and logo of this software are based on the abacus calculation tool. [ 6 ]
CalculiX is a free and open-source finite-element analysis application that uses an input format similar to Abaqus. It has an implicit and explicit solver (CCX) written by Guido Dhondt and a pre- and post-processor (CGX) written by Klaus Wittig. [1] The original software was written for the Linux [2] operating system.
In 2005, Dassault Systèmes sought to improve the quality of 3D interactions and simulations. First they acquired Abaqus, a US-based company specializing in software that allows engineers to simulate and observe the performance of components in products. [8] Then they acquired Virtools, software that enables companies to create 3D applications. [9]
Schematic illustration of idealized fiber arrays and their corresponding unit cells. In the theory of composite materials, the representative elementary volume (REV) (also called the representative volume element (RVE) or the unit cell) is the smallest volume over which a measurement can be made that will yield a value representative of the whole.

Groupe Industriel Marcel Dassault SAS (French pronunciation:; also GIM Dassault or Dassault Group) is a French corporate group established in 1929 with the creation of Société des Avions Marcel Bloch (now Dassault Aviation) by Marcel Dassault, later led by his son Serge Dassault, and led since 2018 by co-founder of Dassault Systèmes Charles Edelstenne.
A neo-Hookean solid [1] [2] is a hyperelastic material model, similar to Hooke's law, that can be used for predicting the nonlinear stress–strain behavior of materials undergoing large deformations.
