Hi ;
I try to modelize different layers with a hole inside 2 of them but I have this error message and I don't know how to deal with... My code is : // Gmsh project created on Mon Mar 28 16:28:26 2011 // all dimensions in mm lc = 2; //0.005; // Definition dimensions // // PVC1 wPVC1=20; hPVC1=20; tPVC1=0.035; zPVC1 =0; lcPVC1=0.2; //PVC2 wPVC2=20; hPVC2=20; tPVC2=0.1; zPVC2=zPVC1+tPVC1; lcPVC2=0.2; //Alu wAlu = 20; hAlu = 20; tAlu = 0.2; lcAlu= 0.2; zAlu=zPVC2+tPVC2; // Definition structure // //PVC1 (layer 3) p1 = newp; Point(p1) = {0, 0, zPVC1, lcPVC1}; p2 = newp; Point(p2) = {wPVC1, 0, zPVC1, lcPVC1}; p3 = newp; Point(p3) = {wPVC1, hPVC1, zPVC1, lcPVC1}; p4 = newp; Point(p4) = {0, hPVC1, zPVC1, lcPVC1}; l1 = newc; Line(l1)={p1, p2}; l2 = newc; Line(l2)={p2, p3}; l3 = newc; Line(l3)={p3, p4}; l4 = newc; Line(l4)={p4, p1}; m=18; Transfinite Line{l1,l2,l3,l4} = m Using Bump 10.0; ll1 = newreg; Line Loop(ll1) = {l1, l2, l3, l4}; //Volume 3 S1 = newreg; Plane Surface(S1) = {ll1} ; VolPVC1[]=Extrude {0, 0, tPVC1} { Surface{S1}; Layers{ {5,5}, {0.5,1} }; //{5,5}=number of layers in the fist X part where X=first value in second brackets }; Physical Volume("PVC1") = {VolPVC1[1]}; //PVC2 (layer 2) p5 = newp; Point(p5) = {0, 0, zPVC2, lcPVC2}; p6 = newp; Point(p6) = {wPVC2, 0, zPVC2, lcPVC2}; p7 = newp; Point(p7) = {wPVC2, hPVC2, zPVC2, lcPVC2}; p8 = newp; Point(p8) = {0, hPVC2, zPVC2, lcPVC2}; l5 = newc; Line(l5)={p5, p6}; l6 = newc; Line(l6)={p6, p7}; l7 = newc; Line(l7)={p7, p8}; l8 = newc; Line(l8)={p8, p5}; Transfinite Line{l5,l6,l7,l8} = m Using Bump 10.0; ll2 = newreg; Line Loop(ll2) = {l5, l6, l7, l8}; //hole p37 = newp; Point(p37) = {20.15, 20, zPVC2, lcPVC2}; p38 = newp; Point(p38) = {19, 19.85, zPVC2, lcPVC2}; p39 = newp; Point(p39) = {19.85, 20, zPVC2, lcPVC2}; p40 = newp; Point(p40) = {20, 20.15, zPVC2, lcPVC2}; l40 = newc ; Spline(l40) ={p37,p38,p39,p40,p37}; Transfinite Line{l40} = 34; ll15 = newreg ; Line Loop(ll15)={l40}; //Volume 2 S2 = newreg; Plane Surface(S2) = {ll2, ll15} ; VolPVC2[]=Extrude {0, 0, tPVC2} { Surface{S2}; Layers{ {5,5}, {0.5,1} }; //{5,5}=number of layers in the fist X part where X=first value in second brackets }; Physical Volume("PVC2") = {VolPVC2[1]}; //Alu (layer 1) p9 = newp; Point(p9) = {0, 0, zAlu, lcAlu}; p10 = newp; Point(p10) = {wAlu, 0, zAlu, lcAlu}; p11 = newp; Point(p11) = {wAlu, hAlu, zAlu, lcAlu}; p12 = newp; Point(p12) = {0, hAlu, zAlu, lcAlu}; l10 = newc; Line(l10)={p9, p10}; l11 = newc; Line(l11)={p10, p11}; l12 = newc; Line(l12)={p11, p12}; l13 = newc; Line(l13)={p12, p9}; Transfinite Line{l10,l11,l12,l13} = m Using Bump 10.0; //hole p41 = newp; Point(p41) = {20.15, 20, zAlu, lcAlu}; p42 = newp; Point(p42) = {20, 19.85, zAlu, lcAlu}; p43 = newp; Point(p43) = {19.85, 20, zAlu, lcAlu}; p44 = newp; Point(p44) = {20, 20.15, zAlu, lcAlu}; l41 = newc ; Spline(l41) ={p41,p42,p43,p44,p41}; Transfinite Line{l41} = 34; ll16 = newreg ; Line Loop(ll16)={l41}; //Volume ll3 = newreg; Line Loop(ll3) = {l10, l11, l12, l13}; S3 = newreg; Plane Surface(S3) = {ll3, ll16} ; VolAlu[]=Extrude {0, 0, tAlu} { Surface{S3}; Layers{ {5,5}, {0.5,1} }; }; Physical Volume("Alu") = {VolAlu[1]}; //Volume 4 (hole) S12 = newreg; Plane Surface(S12) = {ll15} ; VolSi2[]=Extrude {0, 0, tPVC2+tAlu} { Surface{S12}; Layers{ {5,5}, {0.5,1} }; }; Physical Volume("Si2") = {VolSi2[1]} ; If anyone can help me...Because I looked on forum but didn't find anything. Thank you very much in advance. Antoine |
