glad you solved the mesh problem!

about the physics.. i guess you didn't send all case files..anyway i got the zip file at my work and i tried to do a quick run but there were stuff missing for the solver you had chosen..
anyway i tried your case again and i got the error

Floating point exception

when checking the mesh... it seems you got a very small element which is messing up everything... so your blockmesh file should have at least 1 block with wrong vertices..

if you built the mesh somewhere else i guess the case ran fine
