OpenFoam Heat Transfer 65 - multiRegion salome meshing ideasUnVToFoam and splitMeshRegions

[@freemansjtu]

You're a great tutor! Thanks for making these great videos, I look forward to the next steps on multiRegion case setup!

You are my savior...😁

Thank you very much for the tutorial.

Thanks for the tutorial!
I confused a lot about why my mesh couldn't separate into group of faces and volume,finally I found that in 'Create mesh' I don't have the button called 'Create all groups in geometry'.yep I'm using salome9.40 and after upgrade everything has been solved ;)

I wish you could show us how to do this with the snappyHexMesh tool. I am stuck with the wall film modelling with the reactingParcelFoam solver just because I am struggling with the topoSet and extrudeToRegionMesh BS applications.

I am having trouble converting my geometry from solidworks into openfoam for meshing. My problem is that I cant seem to convert the solid body into a completely closed STL file (to ultimately begin blockMesh and snappyHexMesh).
My case is conjugate heat transfer between a solid and a fluid domain. Before going to my fully complex problem, I am attempting to get the workflow down with a simple case (fluid flowing and heating up in a simple pipe)
Maybe you can find the flaws in my procedure, which is outlined below.
SW geometry creation (2 bodies- 1 solid, 1 fluid)  Export each body separately as STEP  import each body in same session of SALOME  partition and create face groups (inlet, outlet, outer wall, interface_fluid-solid) export each face created as an STL  combine all the STL’s into one to create my outer boundary.
When I run “surfaceCheck” on the combined STL, I am getting the error that the surface is not completely enclosed.

Thanks for your nice tutorials
Do you know how to use polyDualMesh for multiRegion cases?

thanks a lot

Hello!
I am having trouble on defining the interfaces as "FaceZones". I did my geometry in solidworks and exported it to salome as a STEP file. For some reason, when I create the UNV file, the interfaces go as "patch". Could you help me? (great content, by the way)

[@henriquebugado]

For those who might be interested, The problem was solved by using the STEP (from solidoworks) geometry to generate the faces(explode > faces), excluding the duplicated faces (the interface between two solids contained two different faces, I excluded one of them and left the other) and then generating new solids from the remaining faces (New entity > build > solid). After that, create a partition with all the geneated solids and the process go on like the video, the interfaces will now present only one face.

Hi Theo, thank you for the tutorial.
Just wondering but, isn' t SHAPER module a better choice for modelling complex geometries?

[@bhootmehra]

hii. Thanks. Is there any option in Salome to subtract one body from the other keeping the tool bodies still there , Its for conjugate heat transfer problems for example An electronic part (solid) being surrounded by a coolant like Air. Using cut function removes the solid totally but i want it there . thanks

Hello Theo ong.
Can you make a video on different types of boundary conditions and how to use them in openfoam.
Thanks in advance

[@burkitbayevarman5435]

can you please help me Sir? I am having a problem with installing OpenFOAM as it is coming with a mistake such as not such a file or direction.

[@burkitbayevarman5435]

@@TheoOngScienceAndEngineering I was able to figure out and I am doing simple simulation in OpenFOAM but it is difficult. If you will make a video in OpenFOAM for conjugate heat transfer, I would be happy and would watch again and again
