Re: Tetgen 1.5

Have tested on fresh (linux) installation (found that one batch of files didn't upload) and added a command line switch for mesh quality.

I think that is about all I can do at this stage.

Hope others find it useful (but it appears not many people are using tetgen)

Re: Tetgen 1.5

Hi Peter, I have tested with a few poly files, but probably worth testing on more. The poly files I have are relatively complex (different regions, holes & boundary conditions) and quite large. The poly files aren't the easiest to create of course. Tested on debian system. I don't have a compile...

Re: Tetgen 1.5

Just an update - I have made working patches for tetgen1.4.3 and this solves my mesh problem (1.4.2 wouldn't mesh my poly). I have made patches for 1.5.1beta1, and this compiles and successfully meshes the test mesh included in the tetplugin directory. However, it segfaults on one of my meshes. If t...

Tetgen 1.5

Hi

Does anyone have a patch to allow tetgen 1.5 to be compiled with Elmergui?

Alternatively is there a script to convert tetgen format to elmer mesh files?

I have a poly that is fine in 1.5 but doesn't work in 1.4

Thanks

Re: -nogui doesn't save tetgen generated mesh

Please ignore.

Putting full path in -o filename fixes the problem.

-o /home/elm/tg_tst/elmer

I'm a little surprised. Not even ./elmer worked
