Default Rotation periodic boundary condition error

FrenzyHasaki is on a distinguished road

I am working on a model but there is an error jumps out. The error is about a fluid-solid periodic boundary condition, and the message is as followed:

| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Both sides of GGI rotationally periodic boundary condition "fluid- |
| pad2" have the same axial or radial position. Possible solutions |
| include: (a) check that the condition is specified properly; (b) |
| check that the rotation axis for the periodic condition is set pr- |
| operly; (c) decrease the value of the expert parameter "ggi perio- |
| dic axial radial tolerance" (default value is 0.01). |

So I read the suggested solution and from my end:

a). My condition is correct. I modified this model from a previously successful simulation

b). Same as a), this part remains unchanged, and the modifications I had did not involve this surface

c). I did not specify such a thing there.

Therefore I am stuck here and I will be grateful if someone could help me with this.
