	I met some problem when using Gmsh.
	It is easy to triangulate a plane within a lineloop. But I need trianglelate a 2D model which has a margin as a lineloop and some inside fixed lines(they can not be changed), just like "pic1", how can I use Gmsh to do this?  How can I init the model in "mytest1.txt"? With the help of tutorial, I just can generate 1D mesh by add points in the lines. I need 2D mesh with adding refine points inside the region and the lines.
	eager for your help.
