`1pnc` disregards `useMoles` in the choice of primary variables
The 1pnc
model uses mole fractions as primary variables regardless of the value of useMoles
. So if useMoles
is set to false
, one has to set Dirichlet conditions still in terms of moles, while sources and fluxes expect masses.
Should we drop the useMoles
switch or implement it properly?
