Re: CFDOF Solver error after decreasing element size

Maybe it is a memory related issue as you suggested. As thschrader mentioned, there could be an issue with memory when using the docker container. It appears to restrict you to 1GB of memory using the default installation. This post may help: https://forum.freecadweb.org/viewtopic.php?f=37&t=52890&...

Re: Pressure boundary conditions not transferred properly to case files

Hi everybody, any time I try to write a case in cfdOF, pressure boundary conditions are not transferred properly to the case files. "Not properly" means, the figures I provide in the user interface are multiplied by ~0.83 0 Pa entered in the user interface remain 0 Pa in the case file time 0 (case/...

Re: Chip cooling ==> new solver available

Hello, The case is attached without the polyMesh folder (too big). The Mesh has been generated with Salome 9.5. The residual control < 10^(-6) for h. It converges in 1800 iterations https://zupimages.net/up/20/51/f3id.jpg In the controlDict file, the postreatment for wall power takes into account t...

Re: Chip cooling ==> new solver available

Hello, Let me share my results on buoyantSimpleFoam solver. First I have mesh with Salome a 3 parts duct, 1000 mm with adiabatic wall for the mixing of the fluid, 2000 mm for the heat exchange zone (heat transfer coef) and 1000 mm more of adiabatic wall for outlet (I read this tip on cfdonline foru...

Re: Computational Fluid Dynamics (CFD) workbench using OpenFOAM

Hello All, I've reached the next lack of understanding stage Another step forward after a thought regarding the selection of Turbulent or Laminar model selection. It turns out that I had been using RANS Turbulence and conducted a Reynolds Number check that suggested Laminar. Got what I took was a b...

Re: Problems with supersonic calculation (airnozzle)

My Problem now is: After trying to run the solver it crashes for no obvious reason (at least to me). And I am not able to interpret the error message correctly. Thats the output after starting the solver: 14:30:19 Selecting turbulence model type RAS 14:30:19 Selecting RAS turbulence model kOmegaSST...

Re: Installation CfdOf / HiSA

Sorry for the late update, house refurb is taking it's toll on my FreeCAD test time. The good news is I now have a Windows 10 box that I can replicate the fault with the Conda build, I also have miniConda to build different environments and a batch file to convert Conda environments into builds on ...

Re: Installation CfdOf / HiSA

Honestly speaking: no clue. As you said just trial and error. In my opinion it should also work properly with the newest Open Foam Release. Bluecfd is mit the most actual one. On my computers, it works fine with the latest OF release. Until I receive some useful assistance debugging this from users...
