[Nek5000-users] Rotational velocity

[nek5000-users at lists.mcs.anl.gov]

Hi,
if you would like to add Coriolis (and centrifugal) acceleration terms 
then these can easily be put into userf as body forces. If you use a 
param-value from the rea file, then the amount of rotation can be set at 
runtime.

If on the other hand you would like to specify a rotating body, then I 
guess you could use the boundary conditions (userbc) on the body to 
impose this rotation.

Best regards,
Philipp
