Dear Meshing Community,

It has taken me a considerable amount of time to complete a hex mesh for fairly complex geometry of a propeller. Upon completion, certain quality metrics I achieved are: Quality: 0.3 and Min Angle: 18. An image of the mesh is also attached below.

However, it is unfortunate that the mesh still seems to have problems that I am unable to fathom. I am running CFD simulations with identical BC's and the difference in results I am getting is remarkable: STAR CCM calculates a thrust of 90 N while CFX calculates the same as 57000 N. Fluent says:

"The mesh contains high aspect ratio quadrilateral, polyhedral or hexahedral cells. The default algorithm used to compute the wall distance required by the turbulence models might produce wrong results in these cells..."
Is Fluent harsh on prism cells?


How can I salvage this? Thanks.
