Hi,

I tried the Transfinite Surface "*" and Recombine Surface "*" to get Quadrangle9 but I still obtained 8 nodes instead of 9 nodes.
Please, how do I get only Quadrangle9 elements as illustrated below with gmesh command line?

3-----6-----2
7-----8-----5
0-----4-----1

Thanks.

Hello, I don't know if it's too late. However, I wanted to ask if it is possible to generate 8 node quads elements mesh with GMSH. I have a file from Lagamine with only 8 node elements. Thank you
