[Gmsh] Mesh not displayed

Hi Bernhard,

your Line Loops are not correct. You should try to define it with the GUI.
For example you should have

Line Loop(145) = {109,111,110};
Line Loop(146) = {113,112,114};

instead of

Line Loop(145) = {109, 110, 111};
Line Loop(146) = {112, 113, 114};

Moreover the end of your Line Loop 143 is really wrong, some of the lines are crossing (104 & 96 , 103 & 96) or superposed.

Cheers,

Dave
