THE SOLVER ADD-ON FOR FLOWSIM PRO

Understand flow.
Without a grid.

Simulate indoor air and water with moving particles — without a conventional volume mesh.

PHYSICS & MATHEMATICS

Continuum physics.
Expressed in particles.

The Navier–Stokes equations provide the physical foundation. GridLess Dynamics discretizes flow using Smoothed Particle Hydrodynamics (SPH): moving particles carry mass, velocity and temperature, with neighbouring particles coupled through a mathematical smoothing kernel.

From continuum
to particle sum.

A field value is approximated from the weighted contributions of neighbouring particles.

Ai≈∑jmjρjAjW(rij,h)

m: particle mass · ρ: density · W: smoothing kernel · h: smoothing length

Applications

Simulation in action.

Airflow,
heat and CO₂.

Explore how supply and exhaust air, heat sources and room geometry interact.
