Thanks for getting back to me Kremella,

I let it run overnight on a transient mode with the settings as below.My velocity contour plot is below (inlet at front face, but also included the symmetry face)

Also below is boundary conditions which could need changing, and a mesh skewness image (I have used an enclosure and suppressed the bodies physics for your reference, the mesh is not the best but only have student package caped at 500,000 nodes but welcome feedback into how to improve it) 

Thanks in advanced,
