Hi I am trying to create a simple geometry and mesh it. I have attached both the image and the .geo (the extension is .txt because cannot upload .geo) file for Gmsh. In the image, there seems to be an overlap in the mesh between two regions as pointed by the arrow. I did a simple check with a Python script and could not find any duplicate elements. Is this just visualization problem by Gmsh or is there something wrong with my mesh. Thank you for your help.

Hi,

If you take a close look at the points you are defining. Some of them are missing the z-coordinate and therefore the gridsize is used as a z-coordinate. You can also observe this visually, some of the coordinates are not on the same z-plane.

Best, Mikko

Thank you very much Mikko, I should have been more careful. I noticed the missing z-coordinate when I was creating a separate geometry which was based on this file, but I forgot to correct it in this file. Thank you once again for your time and effort, really appreciate it. Now I hope this will give me a better result in my slope stability analysis.
Thanks,
Aashish
