Default Meshing bathymetry!

Posts: n/a
Hi everyone

I have plotted points in the 3D domain in Gambit and connected those with the same depth to create lines representing the bathymetric geometry. I have then created a box around this to allow me to apply an velocity input to see what happens to the sea flow as it passes over there varying depths.

Ok. I have meshed all the connecting lines and then tried to mesh the volume, when I encountered a problem. It is telling me;

"face 13 could not be converted to a submappable region"

Could someone tell me what might make a face "un-submappable"?

What are the best settings for meshing a volume like this? Thankyou all

It would probably be easier to use a point-cloud to surface converter in a 3D geometry modeller like Pro Engineer and then export the resultant surface for import into Gambit.

Start meshing the errigular bathymetric face use the tet/hyprid meshing technique. Then try creating a "size function" to start the mesh generation from that face outwards to fill in the volume.
