Mesh improver

samiam1000 · October 19, 2010, 09:44

Dear All,

I am working with Slicer3D and I got a surface mesh of a certain reconstruction that I did.

I have 3 question:

1. which is the right program/tool that allows me to insert a plane in the reconstruction I get?? I start from a TAC and I reconstruct the internal volume of the aorta. But I would like to insert a plane "in the middle". How can I do that?
2. is there a mesh improver? I mean, I do not know the quality of the mesh I can get from Slicer. Can you suggest me a tool to do this? Open-source (or at least free!), if possible
3. which software should I use to build a volume mesh, starting from my surface one? snappyHexMesh or I can find something better?

Thanks a lot,

Samuele.

Hello,

we have an open-source mesher called enGrid (see http://engits.eu/engrid) which I think might be able to do what you want -- if I understood correctly that is. Together with Blender (see http://www.blender.org) it can be used to modify an existing mesh and create a volume mesh with prismatic boundary layers. As always, there is a downside to it: The documentation is still very sparse -- just an epsilon more than non-existent

We do have a discussion forum, however.

Regards,
Oliver

Out of curiosity did you ever try EnGrid for this application? If not what did you use?
