Meshing error

Mlynam · June 8, 2010, 12:29

I am getting an error when attempting to re-mesh my surface and create a volume mesh. The error reads:
orientFaces: Sidedness had an error
has anyone seen this error? I am running version 4.06.011 and using the polyhedral, prism layer, and surface remesher for the model. Any help would be appreciated.

Check if your imported surfaces doesn´t have pierced faces or other errors. Maybe you´ll need to use the surface wrapper tool.

I did inspect the original surface and I couldnt't find any pierced or strangley formed geometry. Also - surface wrapper is out of the question as I have multiple regions in the geometry. Thank you for your reply, do you have any other ideas?

You said you have multiple regions, are they already set or you will split by surface topology to create the interfaces?

Mlynam · June 9, 2010, 12:20

They are already set and the interfaces have been created.

The wrapper can be used on multiple regions if "per-region meshing" is checked in your mesh continua; you won't have a conformal mesh at the interfaces as a result, though.

Ah! I have a mesh. Thank you for your help everyone!

Maybe you want to tell us what the cause for the problem has been? It could also help other users with a similar problem...

Best regards,

abdul099,

I believe I was having the issue because I was applying a single mesh continuim to multiple regions. When I applied the "per-region meshing" option I no longer had the problem. Does that help?

@ Mlynam and abdul099

yes that was the reason. I had the same problem as u abdul099.
I activated "per-region meshing" and now star ccm+ mashed.

thank you so much!

Per region meshing works but if I would like a conformal mesh at the interfaces this will not suffice.
