Re: FreeCAD OpenFOAM unable to create mesh

Thanks for your fast response! I feel so silly. It turns out, you get this error when you try to "Run Mesher", without creating a Mesh case first. I had some cfMesh installation issues after my first attempt, so I reinstalled cfMesh. When I ran the Mesher again, I encountered the error. In short, i...

Re: User experience - Default constraints

It was only accidentally that we discovered that the current implementation of "object U" in the 0 folder at solver start by default sets the boundary conditions for unspecified faces at "slip" (so, by default this applies to the non-inlets, not-outlets or otherwise purposely constrained faces). Ac...

Suggestion: Might it be possible that blueCFD-Core is not yet ready for hisa 1.1.3? Or is it another issue (installation error, FreeCAD bug ...?)?

Any suggestions welcome!

Greetz,

Roland
This should be resolved - please re-install hisa.

Re: Meshing problem on Linux 20.04 LTS

Lastly, I had so trouble using the command: sudo dnf install netgen and ended up downloading netgen (6.2.1804+dfsg1-3build2) manually from the following link: https://www.ubuntuupdates.org/package/core/focal/universe/base/netgen Sorry - this was a typo. It should have been 'apt', not 'dnf' (getting...

Re: Meshing problem on Linux 20.04 LTS

Good day All, I have been using CfdOF with FreeCAD successfully in Windows for various VOF simulations and recently attempted to use Linux 20.04 LTS as OS with the aim to use Microsoft Azure for larger simulations. I have successfully installed OpenFOAM v.7, FreeCAD 0.18.4, the Plot and CfdOF workb...

Re: FreeCAD OpenFOAM unable to create mesh

I am new to FreeCAD, and was very exited to try some of the OpenFOAM tutorials. When running the Mesher (regardless whether cfMesh, snappyHexMesh, or gmsh), the operation never completes. The "Report View" shows: Your choice of mesh element sizes will likely produce a very large mesh. Do you really...

Re: CFD question: ventilation, inlet or outlet?

Hi tschrader, thank you for the info. I was thinking indeed that the flow of extraction (linked to a pump obviously) would be the official "inlet" but that's what I wanted to confirm. I find "inlet" and "outlet" can be rather in-intuitive in some CFD definitions. In such cases as described here, it...
