NKReac is the total number of different types of reactions,
including surface reactions and radiation imprisonment reactions.
NKReac is calculated by counting the reactions defined in
NAMELIST groups. The number of reactions
counted in each NAMELIST depends on the type of arrow (single or
double ended) used in the
reaction field or on the value of the
opposing property and type of species indicated in the
If a double arrow is used in the
reaction field or
opposing = T, the number of reactions is
If none of the species indicated in the
field represents a vibrational series and a single arrow is used to
indicate the reaction direction or, alternatively, if none of the species
product lists represents
a vibrational series and the
opposing = F,
the instruction represents one reaction.
However, if any of the species represents a vibrational series, all the
corresponding reactions are considered.
In the previous version of the manual a formula for counting the reactions was given. However, handling of vibrational groups has been expanded and the previous formula is now valid only for certain types of reactions involving vibrational levels. In the present version of PLASMAKIN several formulas are used to cover other types of reactions and the interested reader must look directly into the code to see the appropriate formula for each case.
