Algor fluid supports mixtures with same fluid (including density and viscosity etc), but not supports mixtures with different material which belongs to territory of multiple-phase flow.
"One can use Algor's CFD to consider mixing of similar fluids (same density), but not the mixing of fluids of different densities." - Pat Tessaro 2/2010

Does this also hold true for the newer program Autodesk Simulation Multiphysics 2012?

Hi,
is it stil not possible to mix two different fluids ?
the help says the following:
what does that exactly mean ? density or viscosity cant be changed, even when trying two similar fluids with different colors set, the error of impossible mixing is given.
is there a possibility to visualize a mixing between 2 gases with different vol - oder massflows ?
thank you.
I believe the statement that you found is for the product "Autodesk Simulation CFD". Sim CFD is a separate product from Sim Mechanical/Sim Multiphysics, and they have their own message board. So if you want to pursue the simulation of mixed fluids, I suggest that you post to their discussion group.
Simulation Multiphysics does have a fluid flow analysis type which is completely independent of Sim CFD. Sim Multiphysics cannot simulate different fluids mixing. I do not recall reading any suggested work arounds or approximations for Sim Multiphysics.
