Solid motion

Martin_Sz · March 13, 2015, 05:04

Hello
Had anyone a practice with solid motion function on solid domains ??
I have a question
If I define solid motion 1 m/s on X
which value I define on wall velocity on fluid solid interface 1 m/s or 0 m/s ??
Defined wall velocity is required when I define solid motion function.
Best regards

anyone help me ??

I am not completely sure. So isn't the best thing to do a quick test case and find out? It will be obvious when you try it.

Isn´t there an option "relative to wall velocity?"

no there are not relative velocity .
There are wall velocity on interface on vectors u, v, w.
