viscosity, dpm particle matter

mooving · January 14, 2021, 04:00

hello,
i have a problem related on viscosity.
in fluid setting, there are equations about viscosity which have one parameter(temperature).
but I'm using dpm model and it seems like particles don't affect fluid viscosity
because the viscosity is the function of temperature.
then i think, at least, it has to affect the flow of fluid.
but it also seems like particles don't affect the flow or flow velocity either.
how can i make particles affect the flow of fluid?

Select the button "interact with continous phase" in the discrete phase model option screen.

thank you for the answer
I checked that, but it still doesn't seem to work...

i selected the discrete phase domain from none to phase2
and the viscosity of mixture changed successfully.
but what does discrete phase domain mean?
