As I remember, I've turned on some general (not MFX) restart option for .rdb file to be written (sorry, but I do not remember now - look at the "Restart solution" section of manual for general...

No, as I said already, I'm not specialist in aerodynamics at all (an in wings phenomena in particular, whatever those exist). All I can say, it is impossible to perform harmonic analysis in coupled...

Then mesh folding has nothing in common with "divergence", as you descrived it. Actually, I do not see some criteria, how you can detect if for 100%. You can try to perform simulation up to the...

It is in the properties of the domain. (although, I did not find it too useful for the mesh morphing problems arisen in my solutions). You can try...

Yes, problems with mesh can cause very different error types. And the problem is that they often hard to identify as problems with mesh (except for folded mesh). One word about terminology:...

It is not neccessary, that ansys is not started although you do not have results.

It is not totally clean for me, what is the problem. But as error is related with reading interface nodes displacements, I would suppose one of the following: 1. For some reason...

Finally, the solution indeed was to use MFRC command. Using the command MFRC,1,0 in solve block (instead of "RECONTROL,DEFINE,ALL,1,0") makes ansys write restart files (*.Rnnn) each time...

Ok, thanks, I'll look at MFRC command (I did not see, that in MFX analysis RESCONTROL command is ignored). Sad, but I cannot try it right now (I'm already at home), so I will continue my challenge...

I'm solving coupled (CFX + ANSYS APDL) problem. For some reasons some times the solution stops occasionally (e. g. due to poor fluid domain mesh morphing). The thing I would like to...
