Hi, I am returning errors when I try to run any BF tutorial. It seems that the ‘SimpleFoam.err’ file is not generated inside the log folder. Any ideas? Below is my error and thank you:
Time = 6
smoothSolver: Solving for Uy, Initial residual = 0.5378333, Final residual = 7.5936467e+024, No Iterations 1000
smoothSolver: Solving for Uz, Initial residual = 0.52501375, Final residual = 3.1806038e+024, No Iterations 1000
Failed to read C:\Users\brobe\butterfly\outdoor_airflow_2d\log\simpleFoam.err:
[Errno 2] Could not find file ‘C:\Users\brobe\butterfly\outdoor_airflow_2d\log\simpleFoam.err’.: C:\Users\brobe\butterfly\outdoor_airflow_2d\log\simpleFoam.err
done!
Also, I am running the latest version of BF from BlueCFD.
Alright, I reinstalled butterfly and have gotten the ‘outdoor simulation’ tutorial working with no errors. Will keep testing. Just to survey…
The ‘Indoor Simulation 2D’ throws a ‘Windows Error’ on the Snappy Hex Mesh after writing it.
The ‘Indoor Simulation’ ends after 202 iterations and then throws the previously mentioned 'could not find SimpelFoam.err (It should allegedly go to 606 according to the tutorial).
So some examples are working while others do not. Is there any guidelines or advice a forum member can offer? Thank you
The message is misleading! It just says it can’t find the error file since there has been no errors. I should probably remove the message for the report. It has been confusing for several users.
Thanks for the reply @mostapha. It seems that there might be some truth in the SimpleFoam.err message as it does not allow the solution to converge. If this error is misleading, what else could be causing every example not to converge after throwing the above error?
Possibly is there a problem with my blueCFD? Here is an image of it.
From what I can see it stops after 1000 iterations which is probably the number of maximum iterations. If you maximize the number then it will keep running.
I am totally clueless what went wrong. I tried to generate the solution but it only run 1 iteration and stopped completely even though I set to end time 600.
The error shows:
"FOAM Warning :
From function virtual void Foam::probes::findElements(const Foam::fvMesh&)
in file probes/probes.C at line 119
Did not find location (117.43934 -101.12856 26.927351) in any cell. Skipping location.
And also:
could not locate “simpleFoam.err” file
I am not too familiar with CFD but the snappyhexmesh run seems normal with no error log. Its only when i run the solution then the error above appears. Would really appreciate any advice on what had i done wrong?
Hi Joey and everyone. Have you found the solution? I’ve also experienced the same error message. The solution stops in iterations 2, while the max iteration was set to 1000. Any advice would be very appreciated.
Hi Astri
Apology for my late response. I read about the version incompatibility of latest Blue CFD-Core (version 2020) which does not work well with Rhino 7. Hence, I replaced with Blue CFD-Core 2017 which then the simulation worked. You may want to try out if you are using the same version I did.
I reactivated this post because, using the CFD-Core 2017 and Rhino 7 it still says this error.
SnappyHexMesh report says “Finished meshing without any errors”
But when I run de Solution, it says in all lines "Did not find location (coordinates) in any cell.
Also I open first the blueCFD-Core 2017 terminal as administrator
I also have this problem where Butterfly fails to read “SimpleFaom.err” file and fails to create a solution. Have tried running in single processor and made sure my BlueCFD Core is the right version (2017-1, also tried 2017-2 but to no avail). Attached below are my files for reference for anyone willing to help. Thank you.
