SimScale platform offers various meshing capabilities to create computational grids. Several algorithms are available for users to create three-dimensional tetrahedral and hexahedral meshes on the platform. Due to robustness and general applicability of applied algorithms, both automated and manual versions of these meshing algorithms are provided. Details for each operation can be found below.
Current meshing strategies available on the platform are:
Besides creating a mesh within SimScale, users have the possibility to use meshes created with others tools by uploading them directly to the platform.
Currently SimScale supports two formats:
- I-DEAS unv (*.unv)
- MED (version 3.0)
- OPENFOAM® native mesh format (ASCII only)
In order to be able to use your meshes successfully the boundaries of your meshes should be specified as well. All the elements (i.e. nodes, edges, faces or volumes) on which you want to apply boundary conditions or assign a material must be grouped before the upload.
UNV/MED Mesh upload¶
Simply select a *.unv file and upload it. You may also pack it either as *.tar.gz file or a *.zip archive. In order to assign boundary conditions you need to create groups of either nodes, edges or faces. If you want to perform a CFD simulation you will only need face groups (also known as “patches” in OPENFOAM®).
OPENFOAM® Mesh upload¶
To upload an OPENFOAM® mesh simply pack the folder constant of the OPENFOAM® case folder and upload it. The constant folder has to contain the polyMesh folder where the actual mesh files are located. You can pack it either as *.tar.gz file or a *.zip archive which can be uploaded. All mesh patches of your polyMesh/boundaries file will be pickable such that boundary conditions can be assigned.
OPENFOAM®’s binary format is not yet supported. Please make sure the mesh is in ASCII format. To make sure the mesh is written in ASCII, please open the file system/controlDict and change the entry writeFormat binary; to writeFormat ascii;
