Hello,<br>
<br>
I noticed one thing in gmsh. I used same single .geo file in multiple<br>
instances of gmsh and tried to generate a mesh. And everytime the number of<br>
nodes and elements were different for same .geo file. Is this a bug or is<br>
that how it should behave?<br>
<br>
Thanks<br>
<br>
Regards<br>
Rakesh Patil<br>

I send the .geo file to better understand my problem. <br>
As you can see, I have in the center a topography, with a lot of 10x10 m <br>
surface. How can I merge it?<br>
Thank you very very muche, for your attention<br>
<br>
