[Gmsh] Structured tet mesh

[OSHIMA Takuya]

Hello Srinath,

I'm not sure if I'm getting what "structured tet mesh" means
correctly, but if the geometry is really a cube, would this be of some
help?

----------
lc = 0.099;
Point(1) = {-0.5, -0.5, -0.5, lc};
Point(2) = {0.5, -0.5, -0.5, lc};
Line(3) = {1, 2};
e1[] = Extrude{0, 1, 0}{Line{3}; Layers{10};};
e2[] = Extrude{0, 0, 1}{Surface{e1[1]}; Layers{10};};
Physical Volume("internalField") = {e2[1]};
----------

Regards,
Takuya OSHIMA
