Hi all!
I have a volume with air and hydrogen. How can I get the mass of H2 in that volume in a moment? I've got the mass fraction in a point but not the mass in the whole volume. Is there a way of getting it directly? Thank you! |

Search for "volint" in the manual.

Yes, I've tried but I just get the total mass and I need just the mass of hydrogen. Could you help me?

Take the volume integral of the density*mass fraction. (i.e. sum of density*mass fraction*volume of control volume).
