Dear Jeremy and Alessandro, Thanks for your input. Well, the simple ellipsoid problem seemed to work for me on my mac this morning. It guess it wouldn’t work yesterday after a long afternoon of frustration.
Anyway, I have a more complex example (see attached) that is causing some strange behaviour. When I run the script I get the following warning (see the first log file as well): Warning : More than two degenerated edges in one model face of an OCC model I am not sure what is causing this or how to get rid of it. Also, I am not sure if it is a problem or not. I can create the 1D mesh without any problem. However, when creating the 2D mesh, the following lines appear (see full log file for complete print out): Info : :-( There are 2 intersections in the 1D mesh (curves 4 12) Info : 8-| Splitting those edges and trying again Info : :-) All edges recovered after 1 iteration I am not sure if this is a problem or not. Any thoughts? At this point, I have not completed the final geometry that I want and am concerned these warnings might lead to other problems further down the track. Any advice would be welcome. Thanks again, Peter. --------------------------------------------------------------------- Associate Professor Peter Johnston (FAustMS, FIMA) School of Environment and Science Griffith University | Nathan | QLD 4111 | Technology (N44) Room 3.19 T +61 7 373 57748| F +61 7 373 57656 Email [email protected] On 5 Sep 2019, 11:38 PM +1000, Peter Johnston <[email protected]>, wrote: Strangely, it works under 4.4.1 on my linux machine.

Today I downloaded 4.4.1 and it no longer works. I am using the Mac version. Regards, Peter.

Da: gmsh <[email protected]> Per conto di Peter Johnston Inviato: giovedì 5 settembre 2019 09:58 A: [email protected] Oggetto: [Gmsh] ellipsoid issue Hello, I am trying to create some ellipsoids in 3D and came across this solution: SetFactory("OpenCASCADE"); Sphere(1) = {0, 0, 0, 0.5}; Dilate {{0, 0, 0}, {1.5, 1, 0.5}} { Volume{1}; } Characteristic Length{:} = 0.1; Mesh.Algorithm = 6; This was posted on the webpage <https://urlsand.esvalabs.com/?u=http%3A%2F%2Fonelab.info%2Fpipermail%2Fgmsh%2F2018%2F011986.html&e=9895bfa0&h=ea70f4cd&f=y&p=y> http://onelab.info/pipermail/gmsh/2018/011986.html ,however, the example appears to be generating one-point curves and so the meshing is failing. I am using gmsh 4.4.1. I would be grateful for any suggestions and/or advice. I used a similar script before and not had this issue. Thanks very much, Peter. --------------------------------------------------------------------- Associate Professor Peter Johnston (FAustMS, FIMA) School of Environment and Science Griffith University | Nathan | QLD 4111 | Technology (N44) Room 3.19 T +61 7 373 57748| F +61 7 373 57656 Email [email protected]<mailto:[email protected]> _______________________________________________ gmsh mailing list <mailto:[email protected]> [email protected] <http://onelab.info/mailman/listinfo/gmsh> http://onelab.info/mailman/listinfo/gmsh
