Hi all,
I hope you are doing well. I am a bit newer in Gmsh meshing. Actually, I was trying to create a square cavity with a structured mesh using Gmsh. Now I need to make a more dense mesh close to the walls inside the square cavity. Please see the picture and geo file attached here. Fortunately, I was able to make a dense mesh on two sides (left and bottom) of the cavity so far. I need to create the same dense mesh close to the other (upper or top) side as well. Is it possible to do it? I think it's possible but I don't know how to do it.

Is there anyone who can help me with this issue? This might be a silly issue for someone but its very important for me right now?

Any help would be appreciated...

Thank you in advance!

Best Regards
Razon

There are different ways to do it with gmsh for example:




Point(1) = {0, 0, 0, 1.0};
Point(2) = {1, 0, 0, 1.0};
Point(3) = {1, 1, 0, 1.0};
Point(4) = {0, 1, 0, 1.0};
Line(1) = {2, 1};
Line(2) = {1, 4};
Line(3) = {4, 3};
Line(4) = {3, 2};
Line Loop(1) = {2, 3, 4, 1};
Plane Surface(1) = {1};
Transfinite Surface {1} = {4, 3, 2, 1};
Transfinite Line {1,2,-3,-4} = 100 Using Bump 0.15;
Recombine Surface {1};

Hi mzzmrt,
