Dear Henk, Thanks for the reply-it answers part of my question, that is, how to mesh the volume between the outer cuboid and the inner STL model.
However, how do I generate a mesh which is fine around the inner surface (the model) and becoming coarse towards the surrounding cuboid?. I tried using the threshold and attractor fields but it seems the latter does not support surfaces: http://geuz.org/pipermail/gmsh/2009/004198.html Is it possible to extract the surface points of the model and use them as attractors?. Thanks, MIke. --- On Thu, 6/18/09, dolfyn <[email protected]> wrote: From: dolfyn <[email protected]> Subject: Re: [Gmsh] Meshing the volume between a model and a surrouding cuboid To: [email protected] Date: Thursday, June 18, 2009, 9:43 PM Dear Mike, Do you mean something like this? http://www.dolfyn.net/dolfyn/gmsh/tutorial07.html Next step with the 'attractor' can be achieved with a background mesh (a todo for me). Enjoy!
