Initial Condition and State
In the Flow Analysis Tree, under
Domains, select a fluid domain to see the
Initial Condition and
State under the
Turbulence module in the Properties panel.
Initial Condition
Initial Condition refers to the values of the independent variables required to start a simulation when you select
Start from Initial Values in the
Run group. For the
Turbulence module, you can specify the initial
Turb. Kinetic Energy and the
Turb. Dissipation rate for each
Volume.
The method for specifying the
Initial Condition for the
Turbulence module is activated for a selected volume under the
Turbulence module.
Specified Values is the only option currently available for the
Initial Condition for the
Turbulence module.
• Turb. Kinetic Energy—Default initial turbulent kinetic energy is one percent (0.01) of the initial kinetic energy.
• Turb. Kinetic Energy Diss. Rate—Default turbulent energy dissipation rate is 1.
State
The
State of a volume within the
Flow module determines whether
Volume and
Pressure are solved (
Active) or not solved (
Blanked) within that volume. The
Velocity and
Pressure field within a
Blanked volume are left as the
Initial Condition.

The Turbulence field within a Blanked volume is left as the Initial Condition.
