Angular acceleration in MRFInterFoam

30na · May 4, 2014, 23:08

Hi everyone,
I'm trying to simulate a rotating CD ( microfluidic disc) in openfoam using MRFInterFoam. So far i've been able to rotate the CD with a constant rotational velocity successfully. In the constants folder in Mrf properties i can set a constant rotational speed in front of omega.
But now i want the CD to rotate with a constant rotational acceleration , if anyone could help me with this i would really appreciate it.

Hi,

Perhaps the files attached can help you.

Another idea will be to use codestream directive, have look to :

Good luck
