[fluka-discuss]: Geofar messages in the output file

Hello everyone,

I am having a problem with runs terminating after a while. This does
not happen for every run (so it depends on the initial random seed).
The messages like the ones below get repeated a number of times before
the run is terminated with the last line saying (*STOP TOO MANY ERRORS
IN GEOMETRY*).

There must be a problem with the geometry but I can't see/find it. When
I look at the point apparently causing the issue (i.e. x =
-1.200576518E+03 y = 8.233880299E+03 z = 6.399128534E+03), I don't see
anything wrong (no errors in geoviewer either). I don't have touching
bodies defined here. What I see is that this point is an interface B/N
two regions but why should this be an issue?

The point in the question is where the blue and magenta lines cross in
the X-Z projection view (top left plot), red and magenta lines cross in
the X-Y projection view (bottom left plot), and where the red and blue
lines cross in the Z-Y projection (bottom right plot).


How do I go about debugging/fixing this 'geometry error'?

Many thanks,
Mina
