CalculiX is an open source explicit and implicit finite element analysis application.
The solver, CCX, was written and is maintained by Guido Dhondt.
The pre and post processor, CGX, was written and is maintained by Klaus Wittig.
The source code, Linux builds, documentation, tests and other resources for CalculiX are available
for download at http://www.calculix.de/
Convergent has bundled a Windows build of CCX, CGX, documentation, examples and test suite.
There have been some changes from the original source, and those modified source files are included.
Some scripts and complimentary applications have also been included. CalculiX for Windows
is supported on Windows 98, NT, 2000, XP and Vista.
An extended version of CalculiX for Windows is available with CAD/CAE translation software and a graphical user interface for launching the CalculiX components.
Note: The authors of CalculiX acknowledge that naming conventions and input style formats
for CalculiX are based on those used by ABAQUS, a proprietary, general purpose
finite element code developed and supported by Hibbitt, Karlsson & Sorensen, Inc (HKS)
(http://www.abaqus.com) and are used with kind permission from HKS. Results obtained
from CalculiX are in no way connected to ABAQUS.
Extended Version of CalculiX for Windows:
While the solver (CCX) and pre/post processor (CGX) are available for download below, there
is CAD/CAE translation software, a graphical launcher
and a CAD file viewer that are only available with the extended version. These translations include STEP, IGES and BREP translations
to STEP, IGES, BREP, VRML, STL and partial translation to FBD. The graphical user interface
launches CCX and CGX jobs and has a wizard to guide the user through the various translators. There are also translators between Abaqus, Gmsh and CCX mesh data.
A download of the extended version of CalculiX for Windows is available for purchase for $35 (US).
A CD distribution is available for $55 (US), which includes download access.
Purchase extended version:
The purchase of an extended version comes with 30 days of telephone support for installation and
downloadable upgrades for six months. All proceeds will be reinvested in CalculiX related development.
This build includes CCX 2.0, CGX 2.0, compiled help file,
test cases and two CAD translation tools (VDA and ACIS to FBD). The CCX build has patches
for bug fixes pertaining to stresses for frequency calculations and the thermal analyses.
