You can try download same case from my git:
https://github.com/j-avdeev/KarmanPimple
The server is not unstable. I just removed the file for some time because it causes most of the traffic on my page (several hundred downloads per month).

Putting it on GitHub without asking and without a link to the original place is not very nice.

i downloaded the case and ran pimpleFoam but Fatal Error..


"Starting time loop Courant Number mean: 0.16928 max: 2.70568 Time = 0.001 --> FOAM FATAL IO ERROR: wrong token type - expected word, found on line 32 the label 1 file: /storage/rababqjt/tutorials/Karmann_OpenFoam/karmann_gridpro_pimple/system/fvSchemes.divSchemes.div((nuEff*dev2(T(grad(U))))) at line 32. From function Foam::Istream& Foam::operator>>(Foam::Istream&, Foam::word&) in file primitives/strings/word/wordIO.C at line 74. FOAM exiting "


do you have any idea how i can solve this error?

I've made some changes and tested it with v1912. So it should work now. Have fun.

its still having a problem, i am running the Openfoam 6 version...



What are exactly the steps to run the simulation? I figure since mesh is already there, we need only to:


1. decomposePar
2. pimpleFoam
3. reconstructPar
4. paraview


are these the correct steps? where is the problem?


thanks!

  1. Edit the file "Allrun_parallel" and remove the # at the beginning of the 7th line
  2. Edit the file system/decomposeParDict and replace the "3" with the number of cores you want to use.
  3. run the "Allrun_parallel" script
  4. postprocessing with ParaView

I made a tutorial, you can find the files in my repository: https://www.youtube.com/watch?v=A1YQ9eZQFcg

thanks, i was struggling with the Allrunscript and how it works, glad to know how it works now :)
