Default Rotating Coordinate System Error

Hi all,

I have a simulation with an object rotating about a point. I am trying to set up a coordinate frame that rotates with the object. I made a new coordinate frame and set the frame motion to 'Rotating'. However, when I try to run the simulation I get this error and the simulation stops:

ERROR #001100279 has occurred in subroutine ErrAction.
Message:
Stopped in routine GET_CBCK_VALUE

Does anyone know what this means/how to resolve it? I know it has to do with the rotating coordinate frame because if I set the frame motion to stationary then I stop getting the error.

Do I understand correct, that you have a fixed point and an object, that is rotating around this point ? And then you created a new coordinate frame that is rotating?
Did you specify the correct coordinate frame for your object in the rotating frame ? If the object rotates around the point P, then you should specify a coordinate frame where the rotating axis goes through P. Have a look if you maybe used the global axis instead of your new axis.

What are you tring to do? Do you have 2 rotations at the same time? Something like a spinning object that rotates around a central point?

What Ansys CFX version are you using?

I think you may also have some expression using the rotating coordinate frame? Say something along

Function(Variable)_x_MyRotatingFrame@Location

Yes, that is correct. I have an object in a domain rotating around a point, and created the rotating coordinate frame at the center of rotation. The center of rotation and the rotating coordinate frame are both at the global origin.

I have a rotating domain which contains the object, and this is rotating around the global z axis. I am trying to make a rotating coordinate frame at the origin so that I can monitor the forces on the object with respect to the rotating frame.

I'm using the 2022 version of Ansys and I do have expressions like that.

Remove the expression, and check how far the setup proceeds.

When the expressions are removed the simulation proceeds normally without errors. Are expressions not able to reference rotating coordinate frames?

As far as I understand, they are not supported as part of the CEL-integrated functions.

Alright, good to know. Thank you!

In CFD post you can create a coordinate frame which can be used in expressions to calculate forces, moments, etc. You can use the syntax as examples for expressions in Pre. Not sure if Pre or the solver manager will eat it, as Opaque explains, but then at least you cannot blame the syntax.
