i am doing CFD analysis of Kaplan Turbine to do that i have to make rotor as rotating body while wall outside the rotor as stationary. i have already made rotor as rotating wall and outside wall as counter rotating wall in no slip default domain but this message keep on showing every time i run execution: plz help!
| ERROR #002100080 has occurred in subroutine CHECK_NORMV.
| The specified velocity vector on the boundary patch
| has a significant normal component at one or more faces. One of
| these face locations is
| (x,y,z) = ( 1.69413E-01, 1.80352E-01, 4.24567E-01).
| The angle between the specified velocity and the element surface is
| 77.622 degrees at this face. This is considered an error because
| it implies that the mesh is moving. The following are possible
| reasons for the error message:
| 1. There is a setup error; for example, an incorrect axis of
| 2. There may be a meshing problem; for example, the nodes on a
| rotating surface might not lie on the surface of revolution.
| 3. The boundary is curved and the mesh is very coarse. In this
| case, you may modify the tolerance by increasing the
| expert parameter 'tangential vector tolerance wall'
| from its default of 20 degrees.
