Hi everyone
In the beginning of last year, I finalized a project about the stability and segregation of fresh concrete during flow/casting at jobsite. For the CFD part of the project, I had to write a solver that combines the Volume of Fluid Method (VOF) with the Drift Flux Model/Method (DFM). The code is for high viscous non-Newtonian fluid and thus does not include turbulence. Since I was also in the full panic of changing job when finished with the project, I didn’t contemplate on announcing the solver part at the time. But here it is anyway.

The manual is perhaps the best part. It goes in step-by-step manner into DFM (chapter 2) and VOF (chapter 3) separately and mixing of the two (chapter 4), so if the solver is not of interest, you might like the manual. It also addresses the relevant rheology of suspensions in chapter 5 as well as theories for segregation (i.e. slip between phases) in chapter 6. List of source code and compilation info are in the appendix. If you are going to use the solver, please read (and understand) the manual first.
