[Gmsh] generating a sequence of meshes

[Jeremy Theler]

What about this?

gtheler at tom:~/run$ cat basic.geo.m4 
Point(1) = {0, 0, 0, lc};     Point(2) = {-0.5, -0, 0, lc};
Point(3) = {0, -0.5, 0, lc}; Point(4) = {0, 0.5, 0, lc};
Point(5) = {0.5, -0, 0, lc};

Circle(1) = {2, 1, 3}; Circle(2) = {3, 1, 5};
Circle(3) = {5, 1, 4}; Circle(4) = {4, 1, 2};

Line Loop(5) = {4, 1, 2, 3};
Plane Surface(6) = {5};
gtheler at tom:~/run$ for i in `seq 1 10`; do m4 -Dlc=$i/10 basic.geo >
basic-$i.geo; gmsh -2 basic-$i.geo; done
