Hi, If I am not mistaken, the transfinite algorithm only handles 4-sided surfaces so you will probably need to split your surface into rectangular blocks for it to work. In that case, you are probably better using extrusions. See the attached example and let me know if it helped.

Dear all, I am trying to make a structured mesh for following algorithm, but I could not make it. And my mesh is still unstructured ! Would you please let me know where I made a mistake ? Many thanks, this is my algorithm: //********************************** Point(1) = {0, 0, 0, 1.0}; Point(2) = {10, 0, 0, 1.0}; Point(3) = {10, 4, 0, 1.0}; Point(4) = {5, 4, 0, 1.0}; Point(5) = {5, 5, 0, 1.0}; Point(6) = {10, 5, 0, 1.0}; Point(7) = {10, 10, 0, 1.0}; Point(8) = {0, 10, 0, 1.0}; Line(1) = {1, 2}; Line(2) = {2, 3}; Line(3) = {3, 4}; Line(4) = {4, 5}; Line(5) = {5, 6}; Line(6) = {6, 7}; Line(7) = {7, 8}; Line(8) = {8, 1}; Line Loop(9) = {7, 8, 1, 2, 3, 4, 5, 6}; Plane Surface(10) = {9}; Physical Surface(11) = {10}; Transfinite Line {2}=5; Transfinite Line {6}=6; Transfinite Line {8}= 11; Transfinite Line {7}= 11; Transfinite Line {1}= 11; Transfinite Line {3,5} =6; Transfinite Line {4} = 2; Transfinite Surface {10}={5,6,7,8,1,2,3,4}; Recombine Surface {10}; Again, thank you all, Best, Gladi, PhD student
