Hi guys,

I am working with Progressive cavity Pump, Its like internal gear where the outer gear is fixed and inner gear rolls inside the outer gear.
I doing a moving mesh with transient simulation.
Could anyone help me how can define rotational eccentric axis in new coordinates (coord 1) to apply "torque_z_coord 1()@Rotor" in results monitor.
Another question, How importance of defining rotor wall velocity, does it affect results?, because I couldn't find an expression to defined rolling action velocity.

Best regards,
-Fahd
