Dear Gmsh team,
I am following the same syntax as https://gitlab.onelab.info/gmsh/gmsh/blob/master/demos/boolean/boolean.geo for generating boolean unioun of surfaces. But however it gives me error as in the subject line. Can you please help me to correctly combine surfaces 1:3 into one surface by a boolean unioun ? SetFactory("OpenCASCADE"); // mesh size description cl_1 = 5; cl_2 = 0.01; Geometry.NumSubEdges = 100; // nicer display of curve var1 = 0.02; var2 = 0.1; // Define Segment coordinates X1 ={0,0.000811,0.001097,0.001233,0.00129,0.001325,0.001335,0.001343,0.001346,0.001347,0.001348,0.001348,0.001349,0.001349,0.001349,0.001349,0.001349,0.001349,0.001349,0.0013487}; Y1 ={0,-2.4,-4,-5.6,-7.2,-8.8,-10.4,-12,-13.6,-15.2,-16.8,-18.4,-20,-21.6,-23.2,-24.8,-26.4,-28,-28.96,-29.118}; Point(newp) = {X1[1], Y1[1], 0, cl_2}; // Line 1 Extrude {var1, var1, 0} { Point{newp-1}; } // Line 2 Extrude {var2, var2, 0} { Point{newp-1}; } // Line 3 Extrude {var1, var1, 0} { Point{newp-1}; } // Define 1 segment l0 = newl; l = l0; nR = #X1[]; p0 = newp; p = p0; For i In {0:nR-1} Point(newp) = {X1[i], Y1[i], 0, cl_2}; EndFor p2 = newp-1; Spline(l0) = {p:p2}; Wire(l0) = {l0}; Extrude { Line{l0-3}; } Using Wire {l0} //left Extrude { Line{l0-2}; } Using Wire {l0} // center Extrude { Line{l0-1}; } Using Wire {l0} // right BooleanUnion(7) = { Surface {1}; Delete; }{ Surface {2:3}; Delete; }; ________________________________ Best Regards, Sathyanarayan Rao, PhD student Earth and Life Institute/Environmental Sciences (ELI-e) Université catholique de Louvain c.037, Croix du Sud 2, Louvain-la-Neuve, Belgium Phone: 010473827 ( intercom 73827) ________________________________
