**PhasicFlowPlus** is a software package for simulating fluid-particle flows. It is a combination of computational fluid dynamics (CFD) and discrete element method (DEM). The fluid is assumedas a continuum phase and the particles as discrete bodies.

Here, DEM calculations are handled using features of[PhasicFlow](https://github.com/PhasicFlow/phasicFlow). It is a parallel DEM package that can be run on multi-core CPUs or GPUs. The equations for the fluid phase arediscritized based on finite volume (FV) and solved using OpenFOAM. OpenFOAM is parallelized based on MPI forbeing executed on multicore CPUs. The fluid-particle coupling (PhasicFlowPlus) uses both parallelization methods, shared-memory and MPI, to leverage the maximum computational resoureces.

Based on the above configuration, PhasicFlowPlus can use the computational resources of a multi-core CPU or use the computational resource of both CPU and GPU.

The following parts are being developed at the moment:

*Coursegraining for CFD-DEM

*Coarse-graining for CFD-DEM

* Resolved solver for CFD-DEM

* Modifying some parts for better functionality and performance
