# demo - .in2d file
# geometry consists of two squares,
# the inner square is made of iron, the outer is not specified (default)
# boundary condition 1 on the outside, 2 on the interface between inner and outer square
# new .in2d geomety files ...
# start with keyword splinecurves2dv2
splinecurves2dv2
# next the refinement factor
2
# keyword points
points
# then the details:
# point nr ( need not be ordered ) --- x-coord --- y-coord --- flags
# the refinement factor is an optional flag, -ref=factor, default 1
# the first, outer square
2 1 0
1 0 0 -ref=10
3 1 1
4 0 1
# here begins the second square
6 0.9 0.1
5 0.2 0.1
7 0.9 0.9
8 0.2 0.9
# keyword segments for the segments
segments
# then the segment information
# domain in --- domain out --- number of points --- points --- flags
# again, the refinement factor is an optional flag, -ref=factor, default 1
# still on the wishlist: give names to the boundary conditions, and have a default value for non-specified bcs
# (similar to materials in subdomains)
