dear Foamers,

I've come across a weird error message: i have a case in which i'm using MRF to simulate the Flow around a propeller blade. in order to reduce grid size i wanted to use cyclic(AMI) boundary conditions and thus subdivide the grid into a wedge like sixth of a tube, where the side cuts of the wedge are connected as cyclics. However, when i'm trying to create the patches using creaPatch, i get this:

AMI: Creating addressing and weights between 20486 source faces and 23761 target faces
--> FOAM Warning :

--> FOAM FATAL ERROR: 
Unable to set source and target faces

has anyone any ideas, or experience with this? all the help is highly appreciated!

best,
