Hello everyone,

I am using an actuator disk with a 'cylinder annulus to cell' set.
My cylindrical channel has an inlet, outlet and no slip at the walls.
The simulation runs fine with this setup as I can see the pressure jump at the disk location.

When I add a shaft (also with no slip) inside the disk with a 'cylinder annulus', the simulation crashes with the following error:

Time = 0
mesh not changed.
Created cellSet actuationDisk1CellSet
Applying source cylinderAnnulusToCell
Adding cells with centre within cylinder annulus, with p1 = (1 0 0), p2 = (1.2 0 0) and outer radius = 1 and inner radius = 0.5
cellSet actuationDisk1CellSet now size 72131
Created cellZoneSet actuationDisk1
Applying source setToCellZone
Adding all cells from cellSet actuationDisk1CellSet ...
cellZoneSet actuationDisk1 now size 72131
End


--> FOAM FATAL IO ERROR:


file: unknown

FOAM exiting

Can someone please advice what's going wrong?

Thanks,
Edward
