eventInfiltration BC

Description

This boundary condition provides a fixed value condition for the velocity variable U calculated as:

U = (constantValue+eventValue) & nf

where constantValue is a constant, eventValue a time-dependent infiltration (linear interpolation between the two closest dates) and nf the normal to the patch.

As for all source terms of the toolbox, negative values indicates that flow is going inside the domain.

Usage

<patchName>
{
    type            eventInfiltration;
    constantValue   -50;
    eventFile       "/path/to/event/file.dat";
    value           uniform 0; // optional initial value (necessary for paraview display)
}

The event values are given in the event file eventFile.
