CalculiX Example

CalculiX is a package designed to solve field problems. The method used is the finite element method. With CalculiX Finite Element Models can be built, calculated and post-processed. The pre- and post-processor is an interactive 3D-tool using the openGL API. The solver is able to do linear and non-linear calculations. Static, dynamic, and thermal solutions are available. Both programs can be used independently. Because the solver makes use of the ABAQUS input format it is possible to use commercial pre-processors as well. In turn the pre-processor is able to write mesh related data for nastran, abaqus, ansys, code-aster and for the free-cfd codes dolfyn, duns, ISAAC and OpenFOAM.

Rescale’s ScaleX platform conveniently runs CalculiX simulations with many cores to reduce computational time drastically. The following example is based on a model of hydraulic network with a pipe connecting two reservoirs.
