Being quite new to using Star-CCM+, I'm still figuring out how to do even the simplest of tasks. I just generated a simple tetrahedral volume mesh with 10 prism layers. Everything seemed fine and dandy until I created a split plane to look at my volume mesh and it looked as if two meshes were created in the same volume (see the images below). I have Growth Rate enabled, with 1 Optimization cycle and a Quality Threshold of 0.4.

Do I need to run more Optimization Cycles? How do I clean up this mesh?

Thanks in advance!

Oh could it be do to Quality Threshold set to 0.4? I think at first I misread the description to mean the mesher aims for cells above 0.4.

Hi B.H,

why would you go for Tet-mesh? are you doing some tool bench marking ??

STAR CCM+ is widely known for its robust and memory friendly polyhedral (or dual) mesh. they have better convergence, easier on computer memory and can capture the geometry much better than a tetrahedral mesh.

I originally chose tets because that is what I used in ICEM. I'll give polyhedral meshing a try. Thanks for the advice!

You are viewing a cut through the cells which looks funny. Make a cell surface instead and you will see the whole cell.
