Hi, <div><br></div><div>I've been using Gmsh to create a surface mesh on a complicated 3D geometry. I have three questions that I could do with some help. </div><div><br></div><div>1. What is the most suitable file extension to use if I want to import a mesh and edit it with Gmsh? The object does not originally come from a CAD source or anything like it. I'm currently using a .stl file but had to convert to that anyway so if there is a more suitable version please advise. </div>
<div><br></div><div>2. In the .stl format I am easily able to refine my mesh however not locally. Ideally I would like the option of picking areas on my surface mesh that would have a higher refinement. Or put another way, points from which the mesh initiates from. </div>
<div><br></div><div>3. The mesh I'm importing isn't necessarily perfect. Is there a way re-creating the mesh to essentially 'clean' it of any hard edges or overlapping that might be present with it? </div>
<div><br></div><div>Any help with this would be greatly appreciated. Great application by the way. </div><div><br></div><div>John</div>
