Our review
Pros	Multi-GPU execution for demanding SPH flow simulations Models free surfaces, surface tension, and multiphase flows Supports fluid–structure interaction and thermal energy equations	Imports major CAD formats and includes geometry editing and data cleaning. Combines flow, heat transfer, radiation, multiphase and motion analysis. Offers multiple mesh types, adaptation and engineering integrations.
Cons	Requires CUDA-enabled NVIDIA GPUs for GPU execution Narrower scope than broad general-purpose CFD suites Licensing uses Altair Units consumed per GPU job	Desktop deployment limits it to Windows and supported Linux systems. Pricing requires contacting sales, so costs need a direct vendor discussion. Its broad simulation scope may exceed the needs of teams seeking basic CFD.
Our verdict	Altair nanoFluidX is a desktop computational-fluid-dynamics solver built around a weakly compressible Smoothed Particle Hydrodynamics formulation. It targets engineering teams that need GPU-focused simulation of single- and multiphase… Read the review →	Cradle CFD scFLOW is a desktop computational fluid dynamics application for engineering teams that need to move from CAD geometry through meshing, simulation and results visualization.
