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
