I've been tasked to simulate taylor couette flow between two concentric cylinders that are rotating, however I'm struggling to get the blockmesh file to work - Its giving me an error saying my faces are pointing inwards but I'm not sure why - I've double checked all the points and it should be fine.

Please see the attached blockmesh below:
