OpenFOAM and CalculiX
DHCAE Tools is proud to announce a support for coupled flow and structural applications in CastNet based on preCICE as coupling system using OpenFOAM (CFD) and CalculiX (CSM) as solvers.
The outstanding features of the preCICE coupling are
Case setup
CastNet enables the user to setup a complete simulation case for OpenFOAM, CalculiX and the preCICE coupling, based on a single CAD geometry input. Meshing and analysis definitions are completely GUI based and associated with the CAD geometry.
In the CFD domain, hybrid meshing with structured mesh regions in areas of high mesh deformation during the FSI coupling are easily realized. For CalculiX linear or curved second order elements are available.
The OpenFOAM and CalculiX solver setups are defined in a GUI based manner. There is no need to have a detail knowledge of the solver specific keywords or to be familiar with the text-
The preCICE coupling setup is realized by an additional GUI entry for the coupling procedure and mesh motion. A wide range of coupling and mapping options in preCICE are supported. The FSI-
Running and monitoring
In runGUI the case is executed and monitored. Beside the typical residual, probes and surface value plots, additional information for the coupling (e.g. number of coupling iterations) are plotted.
The fluid and structural results can be visualized together in a single Paraview session using DHCAE’s vtk-
