Hi Vladimir,
as a further suggestion, you can double check that the cosine directors
of your primary particle are normalized to 16 digits. See also this thread:

I am afraid I cannot change something in phantom geometry. According
to your advice, I established accuracy 0.000000000000000001, but it
gave nothing. I do not know what is meant by messages of type

but there are no error messages.
Of course, I can receive the necessary picture without Flair, but
nevertheless...

Hi Vladimir,--
OK, even if your are able to visualize the geometry correctly, a
GEOFAR error
usually indicates a problem in the geometry. In your case you have many
volumes and there
can be an accuracy problem in the definition of boundaries between them.
Inspecting the
.err file, you find for instance this message:
Geofar: Particle in region 2 (cell # 0) in position
-1.000000000E-11 2.100900010E+01 6.253070334E-02
is now causing trouble, requesting a step of 4.659204660E+01 cm

lagain, lstnew, lsense, lsnsct F F F F
Particle index 0 total energy 0.000000000E+00 GeV Nsurf 0
We succeeded in saving the particle: current region is n. 4 (cell
# 0)
and see that FLUKA has problems in tracking particles from position XYZ
to direction ABC
by a step of S. The error position is given by the vector operation: XYZ
+ S * ABC.
You can do the following:
1. check the volume corresponding to the error position computed as
above;
2. increase as much that you can the precision in the definition of your
geometry,
switching maybe to free format (comma separated WHATs) to have more
than 10 digits precision;
3. reduce a bit WHAT(2) in GEOBEGIN (see manual): this is a parameter
used to define
the boundaries position while tracking and in your case the default
might need to
be readjusted;
4. activate the geometry debugger around the error point ith the GEOEND
card (see manual).
Hope this helps!

Dear Andrea!
I do not think that it is mistakes in Fluka geometry. Calculations
take place without mistakes.
Mistakes generate Flair+GEOFAR.
I can show the page of geometry Flair. There everything is correct.

Hello Vladimir,
I have looked at your files and it seems to me that
there are
errors in your
geometry (I do not have the voxels file and cannot further
investigate
nor reproduce
your error). Please check at the end of the
flairbvvDJY001.out file:
Abort called from GEOFAR reason TOO MANY ERRORS IN
GEOMETRY: STOP Run
stopped!
STOP TOO MANY ERRORS IN GEOMETRY: STOP

Dear Andrea!
I cleaned all fields at Flair Plot, setup all auto, and
got as a
result the same picture without contours and some
Flair's files
(look
at temp.zip).

Hi Vladimir,
I see that you use the geometry Red (front view) at
position 21.
You can try "Auto" and the geometry should be
visible also
with the log
scale.

Yes, I find Aspect under Title. Thank you.
I can show Flair screen (see attachment))

Dear Vladimir,
1. Have you tried to set the Geometry Use
options
(bottom
right in the
plot panel) to "Auto"
or to the name of your project?
2. If you click on "Title" in the plot
panel, extra
options
will be
available: here you can
force an aspect ratio 1 or select
"Auto" to let
Flair do
it for you.
Cheers,
Andrea

Dear Flair experts!
I have two questions of drawing in Flair.
1. Why at setting of the linear scale
of sizes
I can
receive the
picture with contours of bodies
(pict1.png).
But if to
establish
a log
chart, then contours disappear
(pict2.png).
How to keep
a contours?
2. When drawing with identical sizes
on axes
(square)
the picture
looks oblate down. How to correct it?
I thank for the help.
