November 13, 2020 at 8:40 pmroytorcSubscriberCould anyone let me know when to use a mass-weighted average. I'm calculating average value of scalar dissipation rate. Is it suitable?n

February 15, 2021 at 11:33 amAbubakarSubscriberI mean to say that is it ok if I am using an area-weighted average for flow boundary and the mass-weighted average for wall surfacen
