Hello,<br><br>I've started to use Gmsh some weeks ago in order to build a spherical mesh which will be used in BEM (Boundary Element Method) as a field point mesh for an acoustic simulation. The field points can be understood as microphone positions around the object being studied and their coordinates are being generated in Matlab which exports them in the X, Y and Z form. My main problem is that one of the softwares I use for my simulations (Virtual.Lab from LMS) can't understand just the nodes as field points, and a solution for that would be to create a shell mesh with all nodes being connected to their neighbors in order to form quadrilateral elements around the whole sphere.<br>
<br>At the begining I thought this would be an easy task and, although I'm fully able to create nodes and connecting lines in Gmsh, I can't find a solution to my problem and I'd be really thankful if I could make the process of "creating quarilateral elements by connecting adjacent nodes" at least semi-automatic. By now I have 625 nodes, but I'll probably have to increase their number so I'd have a finer mesh needed for my future studies, making any manual method very time consuming.<br>
<br>I'd really appreciate any ideas and/or help and if you need any additional information please let me know.<br><br>Best regards and thanks in advance for your help,<br><br>Lucas Fernando Coser<br>
