Dynamic Parameters

Description

This module allows the definition of specific parameters that are used used runtime.

Syntax

Dynamic parameters are defined in the dynamicParameters sub-dictionary in the phaseProperties dictionary.

• constantFilterSize (optional): use this keyword when the mesh is uniform. When the keyword is present faster algorithms are used when filter size is required.

• referenceFilterSize: requires a number. Specifies the reference filter size to be used in some correlations.

• settlingDrag: requires a string. It's the drag law used to evaluate the settling velocity which is used in some correlations. Valid drag laws are: Stokes, WenYu, KochHill and Beetstra.

Examples

dynamicParameters
{
  //Speed up calculations with constant cell size
  constantFilterSize;

  //Quantities used in correlations
  referenceFilterSize            1e-4;

  //Settling drag law for terminal velocity
  settlingDrag Stokes;
}
