Hi Alessandro,
The LOW-NEUT card is not needed with PRECISION defaults.
With pointwise transport:
- the LOW-MAT card is not necessary.
- the LOW-PWXS card should be used either with individual isotopes (since
pointwise cross-sections are per isotope) or for all materials with WHAT(1)
= 1, as shown in the example on page 174 of the Manual.
To make it work: remove LOW-NEUT and LOW-MAT, your current LOW-PWXS, and
(unless you have a specific reason for using pointwise only for TUNGSTEN)
add LOW-PWXS from that example:
LOW-PWXS 1.0 HYDROGEN _at_LASTMAT
If you want to use pointwise only for TUNGSTEN, redefine this material as a
compound of its individual isotopes and add a separate LOW-PWXS for each
isotope.
Side note: to improve geometry tracking efficiency, optimize your regions
by splitting them into simpler ones, especially the "around" regions.
See slides 41-45 in this lecture:
