[FLASH-USERS] Mass scalar question

[William Gray]

Hello FLASH users,

I have a hopefully simple question. I am wondering what is the correct method of defining a mass scalar. If I have a quantity Z (in my case I am using this to track metals) that I have defined as a mass scalar. Should it be defined as Z = Z_wanted*density or as Z = Z_wanted?  I am interested in this because I want to make sure that this quantity is advected correctly.


Thanks for your help,
