# nanoFluidX Overview

nanoFluidX is a software to simulate single and multi-phase flows based on the Lagrangian Particle Method Smoothed Particle Hydrodynamics (SPH).

The purpose of this code is to simulate complex flows that are difficult or infeasible to handle using classical CFD approaches such as Finite Volume Methods. The main advantages of SPH are the conservation of mass and momentum (linear and angular) in the absence of physical dissipation, for example, due to viscous shear effects and the exact advection of the particles. As a consequence, SPH is very powerful in dealing with free-surface flows as well as multi-phase flows with complex physical phenomena such as surface-tension or interfacial transport processes. Also, using a pure particle representation allows for modeling solid dynamics and fluid-structure-interaction as well.

In case of issues regarding the installation or usage of nanoFluidX please consult the Tech Support at Altair Engineering via email to hwsupport@altair.de or by phone. The contact numbers can be found here.

nanoFluidX follows the weakly-compressible SPH approach (WCSPH). For truly incompressible SPH the particles cannot be updated independently.
