how to model a new material without molar mass value

Pled · September 26, 2018, 09:35

I need to model a particle material, but without the molar mass value.
Specifically, in blood there are monocytes and I want to model these without the molar mass value since it is unknown.

As long as you don't do any chemistry, the molar mass is not used CFX. Only density is relevant. So you can give it any number, it won't affect your hydrodynamics.

At least, this is my experience. Are there different experiences?

So, only if I need them to react, I need to specify a correct molar mass value.

According to my experience: yes.
You can fill in whatsoever. Only relevant is density.
