Hello,<br><br>I'm trying to mesh a complicate geometry using hexas. I succeeded, but sometime it works, sometimes it doesn't. I'm using several Ruled Surface, that according to their definition, are intrinsic transfinite. Those surfaces are not plane. The curves that defines those ruled surface are already defined as Transfinite Lines. For some reason, I get these errors for all of those surfaces.<br>
<br>Error : Surface 100 cannot be meshed using the transfinite algo<br>Info : Meshing surface 100 (Plane, Frontal)<br>Info : Simple recombination algorithm completed (0 s)<br><br>The surfaces are not correctly meshed, and of course, the hexas are not built in the volumes connected to the Ruled Surfaces<br>
<br>Info : Meshing volume 8 (transfinite)<br>Error : Incompatible surface 100 in transfinite volume 8<br>Error : Cannot tetrahedralize volume with quadrangles on boundary<br><br>The weird part. If I reload the .geo file, and mesh it again, it works without problems.<br>
<br>What could cause this? Any parameter or option that I'm not setting, and it is set by default by the GUI? Is there any trick in the defintion of transfinite meshing for Ruled Surfaces?<br><br>This is a problem for me, because I build meshes in batch, using a script and calling Gmsh in terminal mode. In this case, the errors will always occur.<br>
