QBMMlib is an open source Mathematica package for solving populating balance equations with quadrature-based moment methods (QBMMs). QBMMs are used for fully-coupled disperse flow and combustion problems. However, formulating and closing the corresponding governing equations can be complex. QBMMlib makes using these methods simple and accessible:
The algorithm initialization and solution can span just 13 lines of code. Example notebooks demonstrate QBMMlib on bubble dynamics problems.
PyQBMMlib: With Esteban Cisneros I developed a Python version of QBMMlib that leverages JIT compiling for significantly improved performance.

MFC is an open source parallel simulation software for multi-component, multi-phase, and bubbly flows. Its efficient simulation algorithm is capable of solving flows like droplet atomization, bubble cavitation, and their interactions with strong shocks. The simulation method consists of:
MFC is actively developed and gaining capabilities for QMOM-based solutions to sub-grid flows and neural-network enhanced interface capturing.

ECOGEN is an open source fluid flow simulation tool. Interface- and shock-capturing methods handle single-phase gas dynamics and multi-phase and multi-physics flows. Unstructured grids and adaptive mesh refinement (AMR) enable resolution of otherwise inaccessible spatiotemporal scales. Multiphase ECOGEN simulations regularly scale up to thousands of cores. The code base is object-oriented and modular, assisting future development.

PlasCom2 is a variable-order, single- and multi-block (overset), compressible Navier–Stokes solver. It supports curvilinear domains discretized by multiple, overlapping block-structured grids. Hybrid MPI+X and OpenMP handle parallel communication and GPGPU offloading. PlasCom2 utilizes home-grown libraries to manage these interactions:
PlasCom2 routinely scales to all available processing units on the largest machines in the United States, including modern Sierra-like architectures.

RBC3D is a flow solver for soft capsules and cells. It solves the boundary integral form of the Stokes equations via an algorithm tailored for cell-scale simulations:
These features ensure that simulations are robust. Parallel communication (MPI) enables large simulations, such as model vascular networks.
