Hello fluka users,
I am trying to create a simple geometry for a wall made from
intersecting planes,with a vacuum around. My input is at the end of this
message.
It has plotted successfully in SimpleGeo, with the debugger not showing
any errors, and looks like the cuboid I was expecting. However when I
run it in fluka I get a message in the log file: STOP TOO MANY ERRORS
IN GEOMETRY: STOP statement executed.
The fluka geometry debugger hasn't shown any problems although I do get
a message in the .out file:
*** Region # 2 Dnear according to possible overlapping ORs ***
0NGEOM= 4002, NGLAST= 4604
I don't know if this has any relevance to the problem.
If anyone can spot the error in this geometry, I'd be very grateful.
Thanks,
Frances
