<DIV><FONT face=Arial size=2><SPAN class=987472902-13122011>I'm new to Gmsh and
I'm trying to learn the basics from the GUI interface. I'm trying to play
with building a 2-D mesh on a simple box and then inspect the output as I
change mesh parameters. I'm trying to manipulate the average
size of each triangle in the mesh, but the output is not changing.
Here's some of the things I've tried.</SPAN></FONT></DIV>
