Hello GMSH Community,<div><br></div><div>I am attempting to use GMSH to create a unstructured 2D mesh for oceanographic modelling. I am following the tutorial here:</div><div><a href="http://perso.uclouvain.be/jonathan.lambrechts/gmsh_ocean/">http://perso.uclouvain.be/jonathan.lambrechts/gmsh_ocean/</a></div>
<div><br></div><div>I encounter a problem when I attempt to add a 'plane surface' to my geometry. In the tutorial the plane surface is created by individually selecting each boundary including all islands. The problem is that my geometry contains 1000+ islands and individually selecting each will take a very long time. I have attempted to use the lasso selector (CTRL + left click), but this does not seem to work when selecting lines for a plane surface. </div>
<div><br></div><div>So does anyone know a way of selecting multiple lines while defining a plane surface?</div><br clear="all"><div>Thanks very much,</div><br>Clayton Hiles<br><br>
