customer library problem for parallel
 
Dear Foamer,

For the motion of dynamicMesh i wrote a library, which was copied and changed from oscillatingFixedValue. I tested it with single processor, it works fine. But I can not use it parallel. I suppose, something else should also be done, which seems obviously for other people (because I don't find anything about it in internet). Could you please give me a hint?

From your description and your question, I suppose the only logical hint is:
Look at the OpenFOAM source code for ideas! ;)
Specially every application and library related to dynamic meshes.
Good luck!

Hi Bruno,
Thank you very much for your nice replay. The libary works on single processor. Now I want to run it parallel. I try to read the OpenFOAM source code. The problem is, because of my poor C++ I don't even know which one is improtant in this case. :(
Could you please show me an example? Or the problem can not be solved with changing one or two file?
Best Regards,
June

Hi June,

It's easier if you do this the other way around: if you can provide a full example of what you're trying to do, it'll be a lot easier for anyone to help you!

You don't need to provide the code you are working on now, but you should provide at least a small+complete example of the kind of modifications you want to do!

I say this because OpenFOAM is a massive toolbox that can do all sorts of things and we might end up trying to talk about completely different "dynamicMesh" libraries...

Best regards,
Bruno

I guess, without showing any code, nobody will be able to help you out. Maybe you should reveal some of your code?

Otherwise introduce a lot of Info output and figure out, where it breaks.
