10.13.6. Parts - Solvers (Structured) - Solution (2D SPH)

This window lets you set solution options for 2D SPH Parts.

Quadratic viscosity

The coefficient of quadratic viscosity you want to use for SPH computations.

Linear viscosity

The coefficient of linear viscosity you want to use for SPH computations.

Smoothing Length

Specify whether you want to use a constant or variable smoothing length. Using a variable smoothing length is not recommended for most calculations.

Interface treatment

Specify if you want to use Impact/Separation calculations for the treatment of interfaces between different SPH regions.

Note:  The current implementation of the Smooth Particle Hydrodynamics solver has the following limitation for Rigid Body Rotations:

  • The conservation of angular momentum can not always be guaranteed.
