Hi, guys,
I am trying to solve an internal flow problem, and I wish to seperate the mesh for the flow channel into two regions with a surface to ease the post processing.

What I did is that I defined two points respectively located in the two regions with locationsInMesh, but snappyHexMesh returned with an error:

keyword locationInMesh is undefined in dictionary "/home/mzhang/openfoam6/pROJECTS/testlocationsinmesh/system/snappyHexMeshDict.castellatedMeshControls"

I wonder if any of you would please be able to identify where the problem is?

Thanks,
Mingzi

Hello,


Could you fix this problem?

[GerhardHolzinger]

I think the keyword locationsInMesh in only available in the ESI releases of OpenFOAM, i.e. OpenFOAM-20.05 etc.

The foundation release, i.e. OpenFOAM-6 and others, does not support the locationsInMesh keyword.

Is there a way to use ESI releases over Docker? I need to use locationsInMesh and hit the same problem. However, my docker provides OpenFOAM-6.

Thanks!
