Dear All,

I'm working on the domain made of an intake with a rotor of the fan and in that case I have the following message on the interface which could be a problem for the simulations. In fact my simulation stopped after 14 CFX iterations.

The message was as follows:

<img src="info.png">Pitch Change option 'Automatic' has been selected for the domain interface 'R1 to S1'. This option may fail to run in the flow solver if side 1 or 2 of the interface have 360 degree or greater pitch angles, zero radius, mesh faces normal AND parallel to the rotation axis or mesh at the hub curve (low radial or axial position) which are thin in the radial or axial direction.

Please let me know how I can change the option of Automatic!!
Kind regards

Attesz is an unknown quantity at this point
As zhaowei said, set the pitch angles. This is more stable than automatic.
