Improving prism mesh
Hello all,
I have a simple mixing pipe problem that I'm trying to put prisms on. It seems when they approach the BCs (to the right and bottom), the layers collapse. I'm guessing this is because of the fineness of the edges there, but I'm unsure on how to get them right. Also the prisms can't seem to wrap around the two bends on the top and bottom of the pipe shown. I'm pretty surprised the top one didn't work, it's not a very steep slope. Anyone have any tips? Here are some images of my mesh: http://imgur.com/a/eg6FG Also here is my snappy dictionary: Code:

Dear me3840,
here some steps, I would try first: -Refine the base blockMesh; The surface cells seem to have a quite hight aspect ratio in pipe direction -Increase max. refinement level; Might have the same effect as above See, if this helps, otherwise you might want to play around with: -resolveFeatureAngle -Scaling factor of cell layers Best regards Julian |
Hi me3840,
i) play with the snaping parameters. ii) try absolute size (i.e. relativeSize false;) in the layer section in oder to derive a smooth and equally sizede (thickness) layer region. cheers ThG |
