Calculix
Encyclopedia
Calculix is a free
and open source finite element analysis application that uses a similar input format 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. The original software was written for the Linux operating system. Convergent Mechanical has ported the application to the Windows operating system.
The pre processor component of Calculix can generate grid data for the Computational Fluid Dynamics
programs duns, ISAAC and OpenFOAM
. It can also generate input data for the commercial FEM programs Nastran
, Ansys and Abaqus
. The pre processor can also generate mesh data from STL files.
There is an active community online that provides support via a Yahoo! discussion group. Convergent Mechanical also provides installation support for their extended version of CalculiX for Windows.
The CalculiX solver is available on the Sun Grid
.

Computational fluid dynamics
Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with...
