I have a problem for which I am trying to determine the most suitable software to use. Here is a brief description of the problem.

I have a mixture of inertial particles A and B with different properties. I want to inject this mixture into a channel filled with fluid, and observe the transport properties (such as how far the particles travel, height of the settled bed, etc.) as a function of particle properties, concentration, etc.. I expect inter-particle collisions and two-way coupling between fluid and particles to be important to the physics we want to capture. I would also like to use non-Newtonian fluids.

I am looking for suggestions for commercial or open-source softwares that can tackle this problem.

mprinkey will become famous soon enough
MFIX ( can do Lagrangian DEM modeling of different particle sizes and types. It can also do multiple phases of Eulerian solids transport. It is open source, so you can likely use whatever non-Newtonian constitutive laws you like, within reason--It cannot handle viscoplastic flows, for example.

Thank you. I will look into it.

Do you, or anyone else have any experience with the CFDEM workbench ( for this kind of problem?
