iGRAF
iGRAF is an integrated powder and multiphase flow simulation tool that seamlessly merges the domains of powder and fluid simulation. It is designed as a one-stop solution for replicating a wide variety of powder behaviors and redefining standards in simulation technology. iGRAF’s integrated DEM-CFD solver enables accurate and efficient analysis of single-phase and multiphase flow, helping users understand particle-fluid interactions in one platform. Its dynamic geometry control supports translations, rotations, vibrations, and user-defined motion, allowing teams to precisely capture the dynamics of complex systems. It includes validated liquid bridging models and van der Waals forces to analyze the influence of moisture and adhesion on particle behavior, with its liquid bridge force model extensively validated up to 15% moisture content. iGRAF also combines the Signed Distance Function and Immersed Boundary Method to recognize arbitrary solid geometries.

PFC (Particle Flow Code)
PFC, or Particle Flow Code, is a general-purpose distinct-element modeling framework available as two- and three-dimensional programs, PFC2D and PFC3D. It is designed to simulate synthetic granular and solid materials as assemblies of variably sized rigid particles, including disks, spheres, rigidly connected clumps, and convex polygons or polyhedra. It provides an efficient and flexible way to model the motion, interaction, breakage, flow, deformation, and failure of particle systems across geomechanics, mining, civil engineering, materials processing, and industrial design. PFC is especially useful for problems where the behavior of a material emerges from particle-level contacts, bonding, friction, rearrangement, fracture, or flow rather than from a continuous mesh. Users can represent bonded materials such as rock, concrete, or cemented soil, as well as loose granular materials such as sand, gravel, ballast, ore, powders, and grains.

Dive
Dive CAE is a cloud-native computational fluid dynamics software platform that enables engineers to simulate complex fluid behaviors, such as free-surface flow, multiphase interactions, heat transfer, and moving machinery, using a mesh-free Smoothed Particle Hydrodynamics method. It runs entirely in the browser and on high-performance computing infrastructure, so users don’t need local hardware or installation. The mesh-free approach allows for modeling of complex geometry, surface tension, non-Newtonian fluids, and transient flows without the time-consuming meshing and tuning required by conventional CFD. Onboarding is fast (typically under one day), and the software supports parallel design-of-experiment workflows that deliver multiple iterations in hours rather than days. Dive CAE emphasizes collaboration, license simplicity (one licence for all users), transparent cost control, data usage governance, and scalability via cloud infrastructure.

Ansys Rocky
Ansys Rocky is a particle dynamics simulation software that uses the discrete element method (DEM) to model and analyze the behavior of granular materials and particle flows. The platform enables engineers to simulate realistic particle shapes, including non-spherical particles, fibers, shells, and complex material interactions. Ansys Rocky leverages multi-GPU processing technology to accelerate large-scale simulations while maintaining high levels of accuracy. The software includes advanced capabilities such as wear prediction, particle breakage modeling, cohesion analysis, CFD coupling, FEA coupling, and multibody dynamics simulation. Engineers can use the platform to study particle movement, material handling, mixing, separation, and equipment performance across a wide range of industries.
