[Transient Simulation] Angular Velocity dependent on different parameters than time

ThalesMachado · July 28, 2017, 06:08

I'm trying to perform a transient simulation in which my angular velocity is defined by a cell expression which receives an user function with arguments such as Force, time, factor. I give my Angular velocity to a rotating domain.

When I try to run the simulation, I get the following error..

+ Angular velocity can depend only on time for transient simulation+

+--------------------------------------------------------------------+
ERROR #001100279 has occurred in subroutine ErrAction.
Message:
Stopped in routine GET_MOTION_ROTATING

I've read this thread on the Forum .
Troubleshooting probe and average functions with Angular Velocity
Anyhow, I couldn't find a solution.

I tried to edit the parameters rules on /CFX/etc/RULES setting the dependecy list for angular velocity to ANY, however the simulation keeps with the same error.

The simulation works fine for Steady State, so any ideas how to workaround this problem?

The work-around is to stop using rotating frame of reference. The error is there for a reason, if it could handle complex functions for rotational velocities do you think the error would be put in there?

You will have to use moving mesh to do the rotation to make it the complex function as you suggest.
