Dear all,

My case file can be downloaded from the link below (55.0 MB), the largest part of the file is due to the mesh in 'polyMesh' (sorry for the large file size :S)

Essentially I have a basic Francis turbine model (very basic!), and the fluid within my model does not seem to be flowing around the rotor in an expected fashion like that of mixerVessel2D.

Since I'm just a beginner in OpenFOAM, all I did was create separate solidworks parts (rotor & stator), assembled them as a single assembly file (so they would be recognised as separate patch names in paraView), exported as ascii/stl for snappyhexmeshing, placed that mesh in the 'polyMesh', tweaked the '0' file and 'MRFZones' file from MRFSimpleFoam/mixerVessel2D.

Velocity distribution:

Pressure distribution:

Kind Regards,

Mister K
