[Gmsh] Array interval as argument for Plane Surface holes

[Christophe Geuzaine]

Hi Riccardo - Could you send a complete test file? Here this type of syntax seems to work just fine:

Point(3) = {0.9, 0.7, 0, 1.0};
Point(4) = {-0.9, 0.7, 0, 1.0};
Point(5) = {-0.5, 0.2, 0, 1.0};
Point(6) = {-0.5, -0.1, 0, 1.0};
Point(7) = {-0.3, -0.1, 0, 1.0};
Point(8) = {-0.3, 0.2, 0, 1.0};
Point(9) = {0.3, 0.2, 0, 1.0};
Point(10) = {0.3, -0.1, 0, 1.0};
Point(11) = {0.5, -0.1, 0, 1.0};
Point(12) = {0.5, 0.2, 0, 1.0};
Line(1) = {1, 2};
Line(2) = {2, 3};
Line(3) = {3, 4};
Line(4) = {4, 1};
Line(5) = {6, 7};
Line(6) = {7, 8};
Line(7) = {8, 5};
Line(8) = {5, 6};
Line(9) = {10, 11};
Line(10) = {11, 12};
Line(11) = {12, 9};
Line(12) = {9, 10};
Line Loop(13) = {4, 1, 2, 3};
Line Loop(14) = {8, 5, 6, 7};
Line Loop(15) = {12, 9, 10, 11};
hh[] = {14, 15};
Plane Surface(16) = {13, hh[0]:hh[1]};
