Hi all,
i am using sHM since 2 years and after the 7th OF-Workshop I read the sHM-Tutorials of Eugenede Villiers after Bruno told in a thread this nice link. In the presentation there is described the function of "featureAngle". If you set it to 180 you are able to build layers on the corners. I tried this but there is no corner layer. I tried a few featureAngles like: 30 60 120 150 180 but every mesh looked the same? Is that function just implemented in the extended sHM version? Tobi |

Hi Tobi,
AFAIK it works just fine. Just be sure you don't filter any cells by wrong quality settings! Layercells around corners often result in a surrounding mesh that has quite heavily distorted cells. So check your quality setting to allow such cells! G Jan

Hi Tobi,
just to give you an example: I used a cube blockMesh background mesh. Then I put a cube inside this one with SHM and used a few layers. Those layer-cells are colored green. The 1st image is with "featureAngle 50" The 2nd is with "featureAngle 60". This can be a little confusing because the angle is not referring to the two neighboring surfaces the layercells rest on, but to the cells normal vectors of those two neighboring cells. And on a 90° corner that angle is not 90 degrees but less! The last image attached shows how i think the featureAngle works. G Jan

thanks for your replay. Well your post sounds very good but I thought that you get better cells with the layer generation at the corners? Am I wrong? |
