how to mesh a geometry from matlab in gmsh

hi...

as part of my final project i have created the geometry of the cross section of a dam, in matlab, using an isogeometric numerical method code....

i have been asked to use the control points of this geometry, to mesh it on gmsh software, so that to compare the 2 methods, by finding the nodal coordinates and the connective matrix from the gmsh...

i have never used a meshing software before and i am a bit unfamiliar with the concepts of nodal coordinates and connective matrix i am supposed to find....

i know this is a more gmsh and finite element related question, however i would appreciate any help from this blog....

thanks in advance!

It is possible to generate mesh with Gmsh for a geometry from Matlab.

In Im2mesh (an open-source Matlab package), I demostrate how to define 2d geometry in Matlab and then generate mesh with Gmsh.

Please check these two examples: demo14 demo13

To run demo14, you need to install Matlab mapping toolbox, and download Im2mesh package and Gmsh sofware.
