output the species mass fractions

openfoammaofnepo · August 26, 2019, 04:55

Hi All,

For the combustion problems modelled with detailed chemical mechanism, we will typically tens of species or more. In openfoam, all the species mass fraction solved by the equations will be output in the results folders. Is it possible to selectively output some species? Because we are always interested in some of the species and if we output all, they can use lots of data space. Thanks a lot.

Did you start your case already?
I think in paraView you can choose what species you want to see. This option is equal to choose velocity or pressure. For me this works. But I work on mixing problems and not combustion problem.
I hope I could help you.
