Hi sir!
Hello!
Now I have a problem, when I do nonuniform meshing in Cartesian coordinate system, my uniform part coordinates range is 150 to 150m, inside the uniform part, I set the line range is 70 to 70, when I use the mesh size of 10m, my calculation result is as follows, is wrong, I do not know how to solve, when I delete the line part inside, The split turned out to be correct.

Re: nonuniform meshing
Hi sir!
Sorry! I don't clearly express the question. My question is that now I have a trouble with the meshing. I want to construct a model with the nonuniform grid. However, the result is shown in the picture. We obtain a wrong result that the mesh on the left part is nonuniform and the mesh on rest of part is uniform. The minimum grid size what I used is 20m. However, when I delete the blue line, which is the transmitter in simulation, and I get the correct result, i.e. the model is discretized by nonuniform grid.
Best wishes!

Re: nonuniform meshing
I don't fully understand your question, and without the GiD model, I cannot conduct any tests.
Perhaps you could disable the 'automatic correct sizes' preference to have more control over the dimensions. Alternatively, you could make some geometric modifications, such as joining parts. I believe that each bounding box of isolated entities is causing a division on the axis to match this bounding box (with some tolerance to prevent ticks from being too close together).
