I am attempting to mesh CAD origin geometry which was exported as STL. The STL file has multiple issues. Terminal shows this on STL file open
ERROR: TRIG 113468 has 2 neighbours!!!!
ERROR: TRIG 113469 has 2 neighbours!!!!
ERROR: 3860 wrong oriented neighbourtriangles found!
ERROR: try to correct it (with stldoctor)!
So I attempt to correct the orientations with STL doctor by choosing "select triangle" and in Edit Topology I then choose "orient after selected trig"
This generates a segmentation fault. I get the segmentation fault both in Netgen 4.9.13 and the new Netgen 5.0.0
touch triangle 1991, local node 1 (=1312)
Segmentation fault (core dumped)
I am using Ubuntu 12.04 x86_64 and it is up to date. Any advice is welcome.
