ERROR #002100080 has occurred in subroutine CHECK_NORMV.
I'm doing a simulation in a radial turbomachine and I'm getting the following error but I can't find how to solve it. The message from the solver is:
ERROR #002100080 has occurred in subroutine CHECK_NORMV. | | Message: | | The specified velocity vector on the boundary patch | | | | SHROUD | | | | has a significant normal component at one or more faces. One of | | these face locations is | | | | (x,y,z) = ( 3.51842E-02, 1.16276E-02,-9.00251E-02). | | | | The angle between the specified velocity and the element surface is| | 28.124 degrees at this face.

Well, did you check if any of the 3 reasons mentioned applies to the setup of your case?

Some days ago I got the same error due to incorrect axis of rotation definition of my impeller (as the message says at point one). check it carefully.

Hi,
I am also facing the same issue. I am performing a transient analysis (decelerating motion of a brake rotor). My model setup includes a rotating solid rotor, rotating fluid domain and a stationary fluid domain. The angular velocity for the rotor and the fluid domain is kept the same and I am running the simulation in steady state first. I have attached the screenshot of the model set up for further reference. I have checked for all the three possible reasons, the face location specified below. Also, please find the attached output file to this message. | ERROR #002100080 has occurred in subroutine CHECK_NORMV. | | Message: | | The specified velocity vector on the boundary patch | | | | Rotor rotating air Side 1 | | | | has a significant normal component at one or more faces.

Hi everybody,
I faced with the same Error. The problem was wrong Rotation axis at shroud. In fact I defined different Rotation axis in Rotor Domain in comparision with shroud boundary. |
