Class
Foam::functionalFixedValueFvPatchField
Description
Functional fixed value boundary condition using a run-time selected function
to set the value field as a function of space and/or time.
Usage
\table
Property | Description | Required | Default value
value | Value function | yes |
\endtable
Example of the boundary condition specification using the \c zonal function:
\verbatim
<patchName>
{
type functionalFixedValue;
value
{
type zonal;
defaultValue 300;
zones
{
hotFaces
{
type box;
zone
{
type patch;
patch floor;
}
box (4.5 -1000 4.5) (5.5 1e-5 5.5);
value 600;
}
}
}
}
\endverbatim
