{ WINEGLASS_OBJIMPORT.PDE

 

 This sample demonstrates the import of a bounding mesh in OBJ file format.

 It uses the MATERIALS and BOUNDARY CONDITIONS sections to tie names stated

 in the OBJ file to FlexPDE properties.

 

 The OBJ file contains :

   one object named 'glass' that will be bound to a material property set.

   two groups named 'inside' and 'bottom' that will be bound to BC sets.
