Difference between basicMultiComponentMixture and multiComponentMixture
 
Hello all,

can you explain me in short where's the difference between the multiComponentMixture and the basicMultiComponentMixture?

Thank you in advance.

Is there anyone who knows the difference?

Hi,

I know this is 6 years old topic, but I thought it would be useful to have an answer here.


As far as my understanding goes 'basicMulticomponentMixture' is a base class on top of which you stick the more specific mixture models like multiComponentMixture, reactingMixture, etc. (full list can either be found by putting 'dummy' in thermophysicalProperties dictionary file under thermoType 'mixture' subdict, or looking into OF_INST_DIR/src/thermophysicalModels/reactionThermo/mixtures).


basicMulticomponentMixutre is initialized in createFields.H and as far as I understand will necessarily be there if you want to use mixture models, whereas the other subObjects are runtime selectable and specified in the thermophysicalProperties as mentioned above.
