Multimotion in OpenfOAM
 

Hello!

I know that it is possible to do multimotion with OpenFOAM thank's to the multimotion function in the DynamicMeshDict but what is the difference between a single motion and a multi motion regarding the files? In fact when I try to write the files the same way as the single motion ones (which works fine) I can see that the entire mesh moves and then the calculation crashes.
Maybe is it a problem with the use of AMI files because I have 4 AMI faces then.

Do you have an idea?
Thank you.

Hello again!

It's okay I found the error and fixed the problem! I didn't use correctly the function multimotion and the center was not the right one.
