This can be useful when reusing thermo configurations across multiple
setups. In one simulation, the fluid might be entirely air, and in
another there might be additional pollutant or fuel species. This could
be defined without changing the species' thermo enties as follows:
"(mixture|air)"
{
specie
{
molWeight 28.9;
}
thermodynamics
{
Hf 0;
Cv 724.8;
}
transport
{
mu 1.84e-05;
Pr 0.7;
}
}
This was semi-supported before, but it lead to the wrong name (i.e., the
wildcard string) being stored in the base specie class. Now the name is
passed through the thermo constructors, so it is always correct.
