EasyCFD
EasyCFD is a desktop computational fluid dynamics (CFD) application that brings geometry preparation, mesh generation, simulation and post-processing into one graphical environment. It supports two-dimensional and axisymmetric fluid flow and heat transfer, with structured and unstructured meshes and steady or transient calculations.
Users can model laminar and turbulent flow, conduction and conjugate heat transfer, scalar transport, multicomponent flow, and isotropic or anisotropic porous media. Turbulence options include Standard, RNG and Realizable k-ε, SST k-ω, Spalart–Allmaras and Transition k–kL–ω. Results can be examined using contours, vectors, streamlines, XY plots and statistics.
EasyCFD is primarily intended for CFD education and learning, and can also support research and initial engineering analysis. The website provides worked examples, video tutorials, a user manual and validation material. A fully functional 20-day trial is available.

MFiX
MFiX, or Multiphase Flow with Interphase eXchanges, is an open source multiphase flow solver and NETL’s flagship suite of computational fluid dynamics tool for modeling reacting multiphase flows. It has become a standard for comparing, implementing, and evaluating multiphase flow constitutive models, and has been applied to a diverse range of multiphase flow devices and industrial systems. MFiX provides multiple modeling approaches, including a Two-Fluid Model, Discrete Element Model, Coarse-Grained Particle DEM, Superquadric Particle DEM, Glued-Sphere Particle DEM, Particle-in-Cell model, hybrid methods, and a single-phase solver for pure granular flows. These models can be used to simulate gasifiers, circulating fluidized bed combustors, fluidized beds, fluid catalytic crackers, chemical looping combustion systems, and other particle-fluid systems involving hydrodynamics, heat transfer, species transport, and chemical reactions.

Particleworks
Particleworks is particle-based CAE and CFD software for simulating liquid and multiphase flows using the Moving Particle Simulation method. Its mesh-less solver and intuitive interface make the simulation process simple and fast, even for complex geometries with moving parts such as transmissions, electric motors, internal combustion engines, and other industrial systems. Unlike conventional mesh-based CFD, Particleworks discretizes the fluid domain automatically with particles, eliminating complex mesh generation and making it easier to analyze free-surface flow, splashing, sloshing, spraying, mixing, lubrication, cooling, oil behavior, water interaction, and highly viscous fluids. It provides one-stop GUI operation from pre-processing through post-processing, helping engineers set up models, run simulations, visualize results, and evaluate performance in a streamlined workflow.

Orbital Stack
4.5 out of 5 stars
(4 Ratings)
Orbital Stack is an AI and CFD web-based software that provides earlier qualitative guidance, comparing a large number of design options while highlighting any potential wind and thermal comfort red flags. It allows for the realization of a variety of climate-conscious, high-performance developments not previously feasible due to cost and/or time constraints associated with traditional studies.
Orbital Stack is the first digital climate-analysis tool built by global leaders in wind and microclimate engineering using real wind tunnel data. It is truly a game-changer for the architecture and building design sector, offering our clients direct access to wind comfort and safety analysis, thermal comfort and shadowing analysis, and cladding pressure simulations. This means architects can run their own wind simulations and quickly understand the climate impacts of their proposed building designs from the start, making decisions that result in higher performing and more resilient projects.
