The specified velocity vector on the boundary patch |
| |
| r1 |
| |
| has a significant normal component at one or more faces.One of |
| these face locations is |
| |
| (x,y,z) = ( 1.26262E+00,1.02654E-01,3.90449E+00).|
| |
| The angle between the specified velocity and the element surface is|
| 89.755 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 increase the tolerance for this check by |
| increasing the expert parameter 'tangential vector tolerance' |
| from its default of 20 degrees.
