[Netgen] using nglib

vijay.sudharshanam · July 12, 2012, 04:59

Hello everyone.

I'm using nglib to load a CAD geometry in IGES format and generate surface mesh. I want to heal the geometry before generating the mesh but I do not find any healing functions in nglib.h. I tried to dig through the nglib source code and found that OCCGeometry has a healing function called HealGeometry(). But I'm not able to create an object of type OCCGeometry since it generates the compilation error "Undefined symbols: vtable for NetgenGeometry referenced from..." and "vtable for OCCGeometry referenced from...".

Can someone tell me how to create an instance of OCCGeometry in my code?

Greetings vijay.sudharshanam and welcome to the forum!

You better try NETGEN's dedicated mailing list: http://sourceforge.net/projects/netgen-mesher/forums

Because this sub-forum is for how to use NETGEN and other open-source meshers with OpenFOAM.

Best regards,
Bruno
