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 'canincan' that will be bound to a material property set.
two groups named 'inside' and 'outside' that will be bound to BC sets.
title 'Import OBJ can-in-can'
'canincan' : k=1
'inside' : value(u)=1
equations u: div(k*grad(u))=0
boundaries import OBJ 'canincan.obj'
grid(x,z) on y=0
contour(u) on y=0
