Hi Arijit Khan,
You have duplicated mesh nodes, because your surfaces are not
conforming, i.e. their boundaries are different but overlapping lines
(look at the attached picture: the lines 4 and 13 (black numbers)
overlap each other, but they are different lines, therefore the mesh
nodes on them will be different). The solutions are:
1. Get rid of overlapping lines in your .geo file. For example, you can
include the node 4 (red number) of the line 13 in the line 4 (so that
the line 4 will consist of two lines).
2. Read the mesh nodes in your code and get rid of duplicated ones,
while renumerating them with the existing numbers.
3. Maybe there is a Gmsh plugin performing the second approach. But I'm
not sure.
Best,
Mikhail
Hi All,
Greetings of the season.
Firstly, I thank you for this wonderful tool. I am a newbie in using GMSH.
I have created the attached .geo file using Gmsh GUI and meshed it using
Mesh 2D command in the GUI. But it turns out that some of the nodes have
two node number as per the attached .jpeg, this is unacceptable in my FEM
code (this causes a disparity in element connectivity). How do I go about
so that I have one and unique node numbers for each node.
Thanks & Regards
