Problems with icoDyMFoam
 
3 Attachment(s)
Hi!

As some of you might recall, I am currently writing an exam about OpenFoam at my university.
Until now, I managed to set up and solve all the cases I need with MRFSimpleFoam. But now, I want to solve the same cases with icoDyMFoam, and I am just stuck.
I started with the Wiki example (http://openfoamwiki.net/index.php/MRFSimpleFoam).
I set up the mesh like it's done in the tuturial (with the needed modifications for ggi) and then transferred it to OpenFoam.
Quote:

1. fluent3DmeshToFoam
2. faceSet + setsToZones - noFlipMap (to create both zones for ggi)
checkMesh (incl. -allTopology and -allGeometry) didn't show any errors.
To get the needed files, I used the files from the mixerggi tutorial case.
Now I started simulating, and every time my simulation stops at t=0.05.
It doesn't matter what timestep or rpm I use, it always stops at 0.05.
I also set up the case with turbDyMFoam and it stops at t=0.05, too.
Furthermore, I looked at the output in paraView, and it looks good, I don't see any reason why it shouldn't work.
I'm using OF1.5-dev. The tutorial cases worked just fine.
I will attach the logfile and controlDict. If you need anything more, just ask, I'll add it as soon as I can.
I really hope anybody sees some error I don't see and can help me, I would really appreciate it!

Regards,
PaMuelle

I know, pushing my own thread sucks. But does no one have a clue? This project is really important to me and solving this problem would mean a lot. Even small hints about what I should try would help ;)

Do you get any error messages from the code? Or it simply stops? Can you post the screen output?

I attached the Logfile (it's too large to upload here, therefore it's hosted at rapidshare). That's the whole output I get. No segmentation fault or anything else.

Sorry, I missed the log the first time. Sorry, too, that I have no ideas for you. It looks like it stops in the middle of the run loop, so I don't understand why it wouldn't emit some kind of error message somewhere. What variations did you try for the time step and RPM? Could you run the code from a bourne shell and separate stdout from stderr? e.g.

#!/bin/sh

icoDyMFoam 1> out.log 2> err.log
