I'm trying to compare the effect of using a brake duct on an assembly for an open wheeled racing car.

At the moment I only wish to setup a rotating ventilated disc in a stationary domain with an inlet of air at 50ms-1 and an outlet with 0 relative pressure. I am currently just running a steady state simulation and will go on to transient when I can get it working.

I'm working on the principal that a general connection frozen rotor with specified pitch angles of 360 degrees will enable me to see velocity change on a plane through the middle of the disc in post.

I believe that the interfaces are where I'm running into trouble as I get this message 1. The interface contains radial faces (parallel to the axis). |
| If this is the case, please split the interface into two parts, |
| so that the purely radial 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 radial direction is very |
| small (e.g. at the hub or shroud). If this is the case, you |
| may ignore this message. |
+----------------------------

There are 30 cooling veins in the system and I have grouped theese into 4 groups of internal faces namely 'curve left, curve right, is faces and os faces'.
Any remaining faces have been grouped if they are parrallel such as each brake surface of the disc.

I'm currently using a sst turbulence model

Any help would be mcuh appreciated.

Thanks
