Simple Pipe Bend Geometry not converging

Hi all,

I am running a simple pipe bend test case: The geometry is made up of 3 blocks: a 30-diameter long straight pipe upstream of the bend, a 90-deg bend and a 15-diameter long straight pipe after the bend.

Attached are my controlDict, fvSchemes, fvSolution, transportProperties and 0/ files.

Despite all the efforts, I am unable to converge this simulation.

Any help would be very much appreciated,

Z
