Dear all,
I tried to solve a problem but I got the following error message:
0.0: Checking dependencies...
0.0: OpenFOAM case writer is called
0.2: Write OpenFOAM case is completed
0.1: Starting solver command:
0.1: C:\BLUECF~1\OPENFO~1.X\..\msys64\usr\bin\bash --login -O expand_aliases -c cd "/c/users/t42/appdata/local/temp/case" && ./Allrun
0.1: Solver started
5.0: OpenFOAM fatal error: Cannot find file "points" in directory "polyMesh" in times 0 down to constant
5.0: Simulation exited with error
Due to the fact I am new on CFD and CFDOf especially could someone give me a hint whats gone wrong. I have attached the file.
Thanks a lot !!
Best Regards
Marcus

Re: Problem solving incomp. flow
I don't get that error. Make sure that you generate the mesh before running the solver.Sidemountyucatan wrote: ↑Wed Jun 19, 2019 9:27 am Dear all,

I get a different (floating point) exception when trying to run the case. I am fairly sure this is because the mesh is too coarse and no mesh faces on the second inlet. Some refinement should fix it.

Re: Problem solving incomp. flow
Hi olivertoxoby,
I did another trial with a simpler problem just to investigate the "tricks" and challenges. It is simply a diffusor in between
2 pipes. (I did attach the file aswell). Interestingwise I got a error message too but I cannot evaluate why.
204.7: Simulation exited with error
I did mesh refinement. I used snappyhexmesh as net-tool.
Could you take a look to it and tell me why it wont work ? Would really give me help on my way to better understand the matter.
Thx a lot !

Re: Problem solving incomp. flow
… interestingwise I did make a transient run and than it worked ….. can you give me an indication why ? …….

Re: Problem solving incomp. flow
This was an issue with the CfdOF - we were not writing pressure from the potential flow initialisation, resulting in a large imbalance with the 400 kPa boundary. Should be fixed now.Sidemountyucatan wrote: ↑Thu Jun 20, 2019 11:25 am Hi olivertoxoby,
