Hi all. I am running simulations on a compressor fluid domain (Turbocharger compressor for a passenger car) in Ansys fluent 19.3. I am using tetra element and k-omega SST turbulence model. But y+ is still high after refinement. How to reduce to get y plus value
Hi
you can use the inflation layer. by using inflation you are able to make your desire first cell height.
Refinement of the mesh near walls is required.
this can be done either manually or using the refinement capabilities in FLUENT.
Hi,
you could use a combination of refinement on the wall surfaces and then apply inflation layers of your choice ( you may input the first layer height), thus you could generate a mesh of good quality in terms of skewness as well as aspect ratio.
hope it helps.
Regards,
Rajesh.
