Class
Foam::codedFixedValuePointPatchField
Description
Constructs on-the-fly a new boundary condition (derived from
fixedValuePointPatchField) which is then used to evaluate.
Example:
\verbatim
movingWall
{
type codedFixedValue;
value uniform 0;
name rampedFixedValue; // name of generated bc
code
#{
operator==
(
vector(0,0,1)
*min(10, 0.1*this->time().value())
);
#};
// codeInclude
//#{
// #include ".H"
//#};
// codeOptions
//#{
// -I$(LIB_SRC)/finiteVolume/lnInclude
//#};
}
\endverbatim
A special form is if the \c code section is not supplied. In this case
the code gets read from a (runTimeModifiable!) dictionary system/codeDict
which would have a corresponding entry
\verbatim
rampedFixedValue
{
code
#{
operator==(min(10, 0.1*this->time().value()));
#};
}
\endverbatim
