Continuity error
Dear All
I am trying to simulate a raceway pond having a rotating paddle-wheel. I have made the pond a closed tank and considered two phase, water and air, because part of the paddle-wheel is above the water. The geometry was built on SALOME and exported in STL format. I have modified the "mixerVesselAMI" tutorial to setup my case. Running "interDyMFoam" is giving me this error message pasted below that I couldn't remove by changing the boundary condition of U and P_rgh. snappyHexMesh has generated all parts of the geometry similar to the tutorial case. U and P_rgh files are also found below.
Any help please and thank you in advance.
