[mesh manipulation] mesh extrusion

fisch · January 11, 2011, 03:45

Hello Foamers,

is there a possibility to extrude a one-layer 3D mesh (almost like extrudeMesh does) in the direction where currently only one cell exists containing the structure of the boundary patches???

Currently if i use extrudeMesh from one patch it's not conserving my boundary patch structure, and i cant recover it.
So the new cells should be all in different boundary patches (e.g. 6 for a box-bounded problem) finally...

Thanks for your answer!

In my experience this is not possible.

I use autoPatch to split the patch named 'sides' after using extrudeMesh.

After that you can use createPatch to merge patches or create cyclic's.

Hi Steven,

thank you a lot for your reply.
It's working now with autoPatch.
