No meshing
Simply use triangulated CAD surfaces to simulate complex flows around complex geometry.
Unconstrained motions
Free deformations and movement of both fluid and geometry. Ideal for fluid-structure interaction.
High-performance computing
Fully parallel solving on multi-core and many-core devices: CPU, GPU, etc.
Sharp interfaces
Handles violent flows, impacts, fragmentation and surface tension of free surfaces.
Accurate physics
Mass-conservative and validated on various incompressible flows with strong gradients.
Extendable
Extendable to thermal, variable density, and other flows. Name your wishes.
About
RHOXYZ is a Lagrangian and mesh-free general-purpose CFD solver for solving complex flows in complex domains. The fluid body evolves freely in space, interacting with freely moving and deforming bodies. Setting up the simulation completely skips the step of volumetric meshing. Everything is computed in parallel on the GPU or CPU, and free movements allow for large time steps. Appropriate for FSI, optimization studies, improving product performance and end-user experience, reducing cost and extending product life. It is applicable to various problems in marine, automobile, aerospace, civil engineering, defense, and food industries, etc.
