CFD engine · Standalone & Synera add-in
Raphos LBM
Lattice-Boltzmann CFD engine: cumulant D3Q27, LES, FP16 storage, conjugate heat transfer. CUDA or AVX2, standalone or in Synera.
Computational fluid dynamics
A state-of-the-art lattice-Boltzmann solver.
Our own GPU-accelerated CFD engine for external aerodynamics, internal flows and heat transfer — fast enough to sit inside a design loop.
Raphos LBM is a lattice-Boltzmann CFD engine written from scratch at Raphos. It uses the methods behind the current generation of high-performance LBM codes — cumulant collision on a D3Q27 lattice, in-place AA streaming, compressed FP16 storage and interpolated wall boundaries — so that transient, turbulent flows around real geometry run on a single GPU or a laptop CPU.
The engine is a standalone C++ library with a plain C API, so it can be embedded in any tool. It also ships as a Synera add-in, where a virtual wind tunnel is a handful of nodes on the canvas.
