Dear Juan,

The errors are related to the geometry, not scoring. I could not track down the particular error, but can point you to the .err file for hints.
Generally for the use of lattice and other advanced features I would suggest the advanced geometry lecture from the last advanced course
and the geometry exercise with an example of lattice use

As of the EVENTBIN card, it is typically going to be a very large file full of zeroes. Try setting WHAT(1) to -18.0 instead of 18.0 to print only non-zero data, as suggested by the manual page of EVENTBIN. Also keep in mind that this card is meant for fully analogue calculations, the data is printed WITHOUT ANY NORMALISATION.

I hope this is somewhat helpful.

Subject: [fluka-discuss]: Lattice scoring error

Dear Fluka experts,

I am trying to simulate a pixellated silicon detector consisting of very
small cylindrical active areas (11x11) surrounded by silicon. I ran the
program without a scoring card to be sure the geometry was correct and

When using the EVENTBIN card as shown in the .inp file the simulation
stops before completion showing "Abort called from FLKAG1 reason TOO

I have made sure that the geometry is correct: 1- I defined a prototype
region 2-I cloned the outer surface of the prototype region to create
the replicas 3-I am using transformations from the replicas to the
prototype region area (using an inverse traslation that points from the
prototype to the replicas) 4-Each LATTICE card points to its own
prototype and translation card. I do not know if the error is there or
in my scoring card, but I have tried with different cards and the error
remains the same.

Also, is there any information regarding the special scoring of
EVENTBIN/USRBIN? I have not found much information about it either here
or in the courses material.

I would be thankful if someone could point me to my mistake.
