Mesh generation with unstructured grid
Hello everyone,
Hope you all are doing fine. My case is quite simple i.e meshing around an airfoil with unstructured grid. I used Distance
and Threshold
command which gave me satisfactory result to some extent but the problem arises when I decrease the minsize
of the mesh i.e delta x further below 0.0006 (to get the y+ value in the viscous sub-layer). The Gamma
, SICN
,SIGE
min value is in 10^-6 range which is giving abnormal aspect ratio of the mesh generation and somehow the result obtaining is not physical. I guess there will be more efficient way of obtaining the mesh near the wall which gives better mesh statistics and the y+ value remains around 5-10. Even tried with Transfinite curve
but again after a certain range the mesh statistics gave bad result. I'm really stuck at this stage and will really appreciate any kind of help.airfoil_mesh.geo
