One file installation: deploy HELYX-OS and OpenFOAM in your system in one go.Ĭontrol the mesh utility snappyHexMesh, including geometry display and execution within the GUI.Ĭomprehensive case definition module, including controls for physical models, turbulence, boundary conditions and field initialisation.
Gmsh to process stl for snappy hexmesh windows#
Windows version available to paid support customers only). Native support for both OpenFOAM and OpenFOAM+: load existing cases by reading settings directly from the available project text files. The main features of HELYX-OS can be summarised as follows: The GUI provides a fully interactive, easy-to-use environment to perform all pre-processing tasks in the CFD process, including meshing, case definition and solver execution.
Gmsh to process stl for snappy hexmesh manual#
HELYX-OS was created by ENGYS to facilitate the usage of standard OpenFOAM by removing the long and complex manual text inputs required by the utilities and solvers in this code.
