Dear experts of combinatorial geometry:

I have a problem with the attached geometry (with relative input+flair).

It describes a drift chamber where the drifts cells (as defined by wires in reality) are

equivalent in space, from the simulation point of view,to tubes of exagonal cross section.

Each exagonal tube is built by intersecting PLA bodies.

There are 4 + 4 layers of such tube cells (4 per layer)

oriented in two orthogonal directions (U and V cells)

I also attach a picture (the Y-z projection where the U cells are clearly visible).

Flair return no error in geometry.

However at run time, or better, at initialization time, FLUKA crahes

in routine rpnorm:

At line 84 of file rpnorm.f

Fortran runtime error: Index '100001' of dimension 1 of array 'tx' above upper bound of 100000

Backtrace for this error:

+ function rpnorm_ (0x5FF599)

at line 79 of file rpnorm.f

+ function flkcgi_ (0x5EDFA0)

at line 1526 of file flkcgi.f

+ function geoinp_ (0x4E930C)

at line 241 of file geoinp.f

+ function flukam_ (0x409299)

at line 2958 of file flukam.f

+ function fluka (0x40782C)

at line 290 of file fluka.f

+ /lib64/libc.so.6(__libc_start_main+0xed) [0x36f242169d]

I have a certain number of parentheses. but they are not nested!

Is the problem really due to them or to something else?

Thank you for any help

Giuseppe
