Source
In the Flow Analysis Tree, under Domains, select a domain to see the source in the Properties panel. If you select Create a New Source. option under the Turbulence module, you can introduce energy into the Turbulent Kinetic Energy source, Turb. Kinetic Energy Diss. Rate Source Per Volume, or both into a selected Volume.
If no source is created, the source heading is not visible. Multiple sources are numbered sequentially, such as Source 1, Source 2, Source 3, and so on. If you remove a source, the remaining sources are renumbered starting at 1.
Turb. Kinetic Energy Source Per Volume
You can introduce a turb. kinetic energy source per volume for a selected Volume using Turb. Kinetic Energy Source Per Volume. You can add mass as a source per volume (J/m3)/s or a total source (J/s). You can specify a Turb. Kinetic Energy Source Per Volume for an existing Source in a selected Volume under the Turbulence module in the Properties panel. (If no source exists, create one using Create a New Source)
A positive value of the Source Per Volume (kg/m3)/s or the Total Source(kg/s) adds Turbulent Kinetic Energy to the Volume. A negative value removes it.
Turb. Kinetic Energy Diss. Rate Source
You can introduce a turbulent kinetic energy diss. rate source per volume for a selected Volume using Turb. Kinetic Energy Diss. Rate Source Per Volume. You can add Source as a Source Per Volume (1/m-s4), or a Total Source (m2/s4). You can specify a Turb. Kinetic Energy Diss. Rate Source Per Volume for an existing Source in a selected Volume under the Turbulence module in the Properties panel. (If no source exists, create a source using Create a New Source.)
A positive value of the Source Per Volume (kg/m3)/s or the Total Source (kg/s) adds Turbulent Energy Dissipation Rate to the Volume. A negative value reduces it.
Options
A Source listing appears under the Turbulence module in the Properties panel when you create a source using Create a New Source. For the Turbulence module, the possible sources for a selected Volume are Turb. Kinetic Energy Source Per Volume, Turb. Kinetic Energy Diss. Rate Source Per Volume, or both.
Total Source
You can introduce Turbulence module sources (Turb. Kinetic Energy Source Per Volume, Turb. Kinetic Energy Diss. Rate Source Per Volume, or both) for a selected Volume as a Total Source. You can specify a Total Source for Turbulence module sources for the Turbulence module in the Properties panel.
You can add Turbulence module sources as a Total Source.
Source Per Volume
You can introduce Turbulence module sources (Turb. Kinetic Energy Source Per Volume, Turb. Kinetic Energy Diss. Rate Source Per Volume, or both) for a selected Volume. You can specify a Source Per Volume for Turbulence module sources for the Turbulence module in the Properties panel.
