Hello,
I generated a model of a rotating cylinder.
I used the example in icoDyMFoam/mixerGgi in OpenFOAM1.5-dev.
I attached one image of the model (ggi.jpeg).
There is: the rotating patch "cilindro", the fixed patch "wall" and the patches "insideSlider" and "outsideSlider".
When I try to run icoDyMFoam, I obtain:

Quote:

This mesh contains patches of type empty but is not 1D or 2D
by virtue of the fact that the number of faces of this
empty patch is not divisible by the number of cells.

Could anyone explain this error? The empty patches are on front and back of the model. What "the number of faces of this empty patch is not divisible by the number of cells" means?

Thanks in advance for any reply

Andrea

Hello Andrea,

it seems like you declared your defaultFaces to be of boundary type "empty" (look in your constant/polyMesh/boundary file). If this assumption is correct change "empty" in that file to the proper boundary type (e.g. "patch", "wall", ...) . When you did that, change your initial conditions in 0/ and the Error Messgae from above won't appear.

Best,
Andreas
