Hi neks,<br>
Is there a way to specify rotation on a body without mesh deformation? A<br>
follow up question to that is..suppose I specify an Omega a value. Omega is<br>
rotational velocity. How does nek know that this is rotational and not<br>
translational?<br>
<br>
<br>

Hi,<br>
if you would like to add Coriolis (and centrifugal) acceleration terms<br>
then these can easily be put into userf as body forces. If you use a<br>
param-value from the rea file, then the amount of rotation can be set at<br>
runtime.<br>
<br>
If on the other hand you would like to specify a rotating body, then I<br>
guess you could use the boundary conditions (userbc) on the body to<br>
impose this rotation.<br>
<br>
Best regards,<br>
Philipp<br>
