flagellar simple model

I tried to do cfx...about simple model . but error occurred...below

ERROR #002100080 has occurred in subroutine CHECK_NORMV. |
| Message: |
| The specified velocity vector on the boundary patch |
| |
| flagellar |
| |
| has a significant normal component at one or more faces. One of |
| these face locations is |
| |
| (x,y,z) = (-1.28645E-05, 7.93950E-06, 2.45104E-05). |
| |
| The angle between the specified velocity and the element surface is|
| 21.089 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 |
| rotation. |
| 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.

solid part is wall rotating at an angular velocity.
and outlet applies to opening, the oters are general wall.
and it is filled with water.
