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 :
two objects named 'cube1' and 'cube2' that will be bound to material sets.
three groups named 'left', 'middle', and 'right' that will be bound to BC sets.
title 'Import OBJ Cube2'
'cube1' : k = 1
'cube2' : k = 5
'left' : value(u) = 1
'middle' : natural(u) = 0
'right' : value(u) = 10
equations u: div(k*grad(u))=0
boundaries import OBJ 'cube2.obj'
grid(x,y) on z = 0.5
contour(u) on z = 0.5
elevation(u) from (0,0.5,0.5) to (2,0.5,0.5)
