Regarding Delauyny Mesh
 
HI All

could anybody tell me why the Delaauny approach will not mesh if there are more than one Material points.OR can anybody let me know what is the best practice to use Delauny Mesh method if there are more than one material point

Delauny mesher will mesh more then one material points. Can you tell what is exactly your problem.

HI Jeevan

If you have Box (Box1) inside a Bigger box(Box2).I will assign two different Material points say Mat 1 and Mat 2 .But if do Meshing ICEM will volume mesh either one of the boxes not both. But if mesh the inner box first and than other box latter fluent will treat the separating wall as interface but i want to set that as interior

Thanks for the reply

I think you can "form new part" in DM and then treat as one part two geometries

HI Sarah

what do u mean by DM? i am using ICEM-CFD

ICEM CFD Delaunay Tetra will handle multiple material points in multiple domains... if they all touch the outside, you don't need to do anything special. But if they are internal domains, you need to turn on an option...

Just go into "Mesh (tab)=> Global Mesh Setup => Volume Meshing Parameters".

Set the mesh method to "Quick (Delaunay)".

Then go down in the DEZ (data entry zone) and turn on the option for "Mesh internal domains".

You might also want to turn on "Flood fill after completion" while you are there...

Best regards,

Simon

Hi Simon

It looks like the correct approach.Thank you so much for the help
