Hello,

I get the following error massage by running interDyMFoam in parallel:

My grid has two cells in the third dimension, the other two dimensions have a lot of cells.

The grid is a rectangular channel. Bottom and top are walls.

My boundary conditions are:
timeVaryingMappedFixedValue for gas and liquid
inletOutlet for outlet
fixedValue for wall
symmetryPlane for frontAndBack

Has anybone an idea what is going wrong?

Thanks a lot
