I have been testing with the demo file cube.geo:
lc = 0.3;
Point(1) = {0.0,0.0,0.0,lc};
Point(2) = {1,0.0,0.0,lc};
Point(3) = {1,1,0.0,lc};
Point(4) = {0,1,0.0,lc};
Line(1) = {4,3};
Line(2) = {3,2};
Line(3) = {2,1};
Line(4) = {1,4};
Line Loop(5) = {2,3,4,1};
Plane Surface(6) = {5};
tmp[] = Extrude {0,0.0,1} {
Surface{6};
};
Physical Volume(1) = tmp[1];
I generate the mesh file at the command line like this:
gmsh -3 cube.geo
on a Windows 7 machine and on Ubuntu 16.04. The gmsh version is 4.3.0.
I find that the meshes created on the two systems are a bit different. On
Windows the mesh has 137 nodes and 372 elements, while on Ubuntu it has 136
nodes and 373 elements.
Should I be concerned about this?
Thanks
Gib
