Bad Single Cell Projection on a Quilt!
2 Attachment(s)
Hi there,
Dear Pointwise's folks, Please help me figure out this issue because I am tired and out of ideas. I have a structured surface mesh which is very very fine and I am projecting the surface mesh on a quilt before or after assembling a block in a very classical old fashioned way by just selecting 6 surface meshes. The problem is that only one cell on the surface mesh jumps or stretches in a very bad way at some point far away from its original position over the plane and creates a series of negative volume cells. Please check attached pics. This happens only if I project the surface mesh. If I don't, there'll be no problem. I used closest point + project points like this: pw::Entity project -type ClosestPoint -interior [lindex $bdom_lastb($i) 1] [lindex $brackets $i] Do you have any ideas how to project this domain on the quilt without making that particular cell stretches in that atypical way? This is a very very fine grid I have 886,495,296 cells only on this bracket. Cheers, Pay |

I solved this. I am not sure why Pointwise didn't like the way I was assembling my blocks and projecting domains over the quilts. But I rewrite that whole part of script in a different way and now there is no problem. I dunno if this problem happened because I had a very fine surface mesh being project on a quilt, or if there was a bug in my script, or it was something to do with the CAD file. All I know, I haven't change the CAD and got it work by re-writing the script in a different way and assembling smaller blocks each time. I got to generation total: 3,267,183,584 cells on my desktop with 64 GiB RAM. |
