Question about Dependency List of Angular Velocity
 
Hello everyone.
I would like to pass Additional Variables to the User CEL Routine as arguments, then use the Returned Value as the rotation speed(Angular velocity) of the rotating domain.
But it will appear the following errors:

Error processing expression 'Angular Velocity'.
The expression is invalid because:
AV Mz is not available for use in this term
AV Omega is not available for use in this term
Error processing expression: Angular Velocity = Omega


I know Angular velocity’s Dependency List is limited.
What I am confused is the problem still can’t be solved with the help of User CEL Routine.
I need some guidance and advice. Thanks in advance!

If you are trying to use this - are you aware that the reason this error message comes up is that changing angular velocity is not fully supported by the solver? I am pretty sure the terms involved in angular acceleration are nto included. So these terms will have to be insignificant for your approach to be accurate.
