Well, can you try both GMSH 2.0.8 and 1.65 on the attached file containing only flat surfaces? <br><br>For me:<br>1) GMSH 1.65, took 2 min 20 sec., 624 MB max mem<br>2) GMSH 2.0.8, took 16 min using MeshAdapt+Delauney, 147 MB max mem
<br><br>so the speed is degraded by a factor of 8 (bad), but the memory is divided by 4 (good).<br><br>On the other hand, is the daily release available? where?<br><br>Ides<br><br><div><span class="gmail_quote">On 7/18/07,

idesbald van den bosch a écrit :<br>> Hello dear GMSH users,<br>><br>> I am a GMSH user since quite a while now, and I have a question<br>> concerning the 2.0.x series. It seems that v2.0.X is much more<br>> RAM-memory efficient than its
v1.65 counterpart. Unfortunately it is<br>> also much slower (~3 times from my limited experience).<br>><br>The 2D mesh generator is slower, but I think it is more robust and<br>enables to mesh general curved surfaces (NURBS ...).
<br>In the daily release, I have put back a classical isotropic delaunay<br>that is much faster even than the v1.65 triangulator. Yet,<br>it only works for planar surfaces for now, and for meshing the sphere<br>(look at the attachement). When I'll find some time, I'll
<br>generalize this algo for general curved surfaces.<br><br>Normally, the 3D algorithms are much faster and more robust that the<br>ones of previous releases.<br>> 1) does anyone have the same observation?<br>> 2) is the slowness a necessary trade-off for memory efficiency?
<br>><br>No, it's just the algorithm.<br><br>> Thanks<br>><br>> Ides van den Bosch<br>> Bilkent Computational Electromagnetics Lab<br>> Bilkent, Ankara<br>> Turkey<br>> ------------------------------------------------------------------------
