Detailed Description

This functionObject tracks a particle cloud in the specified velocity field of an incompressible flow (laminar, RANS or LES).

It may be used in conjunction with any transient single-phase incompressible flow solver such as pisoFoam or pimpleFoam and tracks the particles or parcels without affecting the flow-field.

The cloud requires the density of the fluid which is looked-up from constant/phaseProperties dictionary and the acceleration due to gravity which is read from the constant/g file if present or defaults to zero.

The cloud properties are read from the constant/<cloudName>Properties dictionary in the usual manner.

Example of function object specification:

    particles
    {
        libs        ("liblagrangianFunctionObjects.so");
        type        particles;
    }

Usage

Property	Description	Required	Default value
`type`	Type name: particles	yes
`U`	Name of the velocity field	no	U
`cloud`	Name of the cloud	no	cloud
