Detailed Description

This boundary condition can be applied to assign either a pressure inlet or outlet total pressure condition for a fan.

Usage

Property	Description	Required	Default value
`fanCurve`	fan curve function	yes
`p0`	environmental total pressure	yes

Example of the boundary condition specification:

    inlet
    {
        type            fanPressure;

        fanCurve        table;
        file            "$FOAM_CASE/constant/pressureVsQ";
        format          csv;
        nHeaderLine     1;
        columns         (0 1);
        separator       ",";
        mergeSeparators no;
        outOfBounds     clamp;
        interpolationScheme linear;

        direction       in;
        p0              uniform 0;
        value           uniform 0;
    }

    outlet
    {
        type            fanPressure;

        fanCurve        table;
        file            "$FOAM_CASE/constant/pressureVsQ";
        format          csv;
        nHeaderLine     1;
        columns         (0 1);
        separator       ",";
        mergeSeparators no;
        outOfBounds     clamp;
        interpolationScheme linear;

        direction       out;
        p0              uniform 0;
        value           uniform 0;
    }

The above example shows the use of a comma separated (CSV) file to specify the condition.
