Detailed Description

Freestream velocity condition to be used in conjunction with the single rotating frame (SRF) model (see: SRFModel class)

Given the free stream velocity in the absolute frame, the condition applies the appropriate rotation transformation in time and space to determine the local velocity using:

\[ U_p = cos(\theta) U_{Inf} + sin(\theta) (n \times U_{Inf}) - U_{p,srf} \]

where

\( U_p \) = patch velocity [m/s]
\( U_{Inf} \) = free stream velocity in the absolute frame [m/s]
\( \theta \) = swept angle [rad]
\( n \) = axis direction of the SRF
\( U_{p,srf} \) = SRF velocity of the patch [m/s]
Usage
Property Description Required Default value
UInf freestream velocity yes
relative UInf relative to the SRF? no

Example of the boundary condition specification: 

    <patchName>
    {
        type            SRFFreestreamVelocity;
        UInf            uniform (0 0 0);
        relative        no;
        value           uniform (0 0 0);    // initial value
    }
