Dear All, I have created a stl mesh using open3D from point cloud. This mesh was split into two domains as a patch using Paraview Python and then added back using "surfaceAdd". Now, this mesh is implemented into snappyHexMeshDict of OpenFoam solver. I mesh is running well. But, when I do splitMeshRegion after some topoSet addition, it creates multiple domains, where my cellZoneRegion has only two regions and I need only these two regions. The splitMeshRegion creates an extra domian which needs to be eliminated or added to the major region. How to do that? I have attached an image where the red color represents the extra domian created. It has only 3 face.
I am running chtMultiRegionSimpleFoam, so needed regions for simulation. Below is the snippet of splitMeshRegion.
Region Zone Name
------ ---- ----
0 1 gland
1 0 tumor
2 -1 domain2
Sizes of interfaces between regions:
Interface Region Region Faces
--------- ------ ------ -----
0 0 1 278
1 0 2 3
You can give try with Salome to split the .stl file and then mesh with snappyHexMesh.
Also. instead of topoSet try setBatch to assign the domain. It may solve your problem.
Dear P. Madhan Kumar ,
Thank you so much for the suggestion.
1. Can you shed a light on setBatch.? If I am not wrong, does it come under foam-extend? Since, I haven't worked with foam-extend, can u shed a light on this?
2. Is it possible to automate the process with salome using python? Currently, I am using Paraview python and automating the process. I will try to work with salome and this.
Regards,
Sunag R A.
setBatch is available in the foundation version of OpenFOAM. I have used that in versions 4.0 and 5.0.
Yes, automation is possible in Salome using python.
Sunag Rattehalli Amaranath Do you know how to divide blockmesh into two unconnected computing domains?
