How to modify high aspect ratio's of imported stl
Verfasst: Di 11. Sep 2012, 16:21
Does anyone know a free solution to altering high aspect ratio of facets typically produced in cylindrical 3D models.
As i show, in Tetgen meshing the solution is very complex / irregular and can cause computation problems. However, it doesn't alter the facet length, so the curve has the original stl imported accuracy which produces
good hole stress plotting.
In NetGen meshing, the stl is converted into coarse facets which leads to higher stress results compared to Tetgen - its easy to see why.
Please see the images. ( this is my first try at image loading - so there might be a delay.)
Netgen corner stress: 1 of 2
Netgen corner stress: 2
Tetgen corner stress: 1 of 2
Tetgen corner stress: 2
Some of the images have been cut of by the photo hosting provider - i hope all is understood.
looking forward to any helpful answers..
