CFD Post Expressions

Hi,

In my simulation i have air and sand particles.
I am trying to access the density of sand in CFD Post, but, not getting it.
I am able to access mass flow rates, velocities etc.
Can anybody suggest me how to write expression for accessing densities of components?

Thanks

Have a look in the CFX reference guide.

You have variables <Particle Type>.Total Particle Mass and <Particle Type>.Mean Particle Diameter, you can work out densities from that.

Dear Glenn,

Ofcourse, the particle diameter is available, but, I don't find anything like total mass.

Thanks

I just told you what the particle mass variable is.
