Hello
There is two warning before solution and solution not running. Help me?

1- Automatic generation of default interfaces is not currently active. This feature can be activated via either the 'Edit > Options > CFX-Pre > General' editor or the 'Case Options > General' editor in the outline tree.

2- In Analysis 'Flow Analysis 1' - Domain Interface 'R1 to S2': Pitch Change option 'Automatic' is not valid if side 1 or 2 of the interface has a 360 degree or greater pitch angle, zero radius, mesh faces normal and parallel to the rotation axis, or mesh faces at the hub curve (low radial or axial position) which are thin in the radial or axial direction.

SOLUTION Error:
| ********* WARNING ********* |
| Coordinate transformation of interface |
| S2 to R1 |
| into a radial interface resulted in some faces with a very small |
| axial extent. There are two possible reasons for this: |
| 1. The interface contains axial faces (normal to the axis). |
| If this is the case, please split the interface into two parts, |
| so that the purely axial sections could be transformed |
| properly. The transformation type (axial or radial) is chosen |
| automatically based on the largest interface extent. |
| 2. This message may be generated because of a tolerancing issue |
| when the mesh resolution in the axial direction is very |
| small (e.g. at the hub or shroud). If this is the case, you |
| may ignore this message. |

Warning 1 : easily fixed following the message.
Warning 2 : just a reminder for paying attention to pitch change angles.
Error : your geometry at the R1/S2 interface looks wrong.
