- easier support for non-mandatory functions. In some boundary conditions it can be desirable to support additional functions, but not necessarily require them. Make this easier to support with a Function1, PatchFunction1 NewIfPresent() selector. - support for compatibility lookups - harmonize branching logic and error handling between Function1 and PatchFunction1. ENH: refactor a base class for Function1, PatchFunction1 - includes base characteristics, patch or scalar information ENH: additional creation macros - makeConcreteFunction1, makeConcretePatchFunction1Type for adding a non-templated function into the correct templated selection table. makeScalarPatchFunction1 for similarity with makeScalarFunction1

Foam::Function1Types::Scale
|
|
|
|
Description
|
|
Function1 which scales a given 'value' function by a scalar 'scale'
|
|
function.
|
|
|
|
This is particularly useful to ramp a time-varying value by one of the
|
|
monotonic ramp functions.
|
|
|
|
Usage for a vector:
|
|
\verbatim
|
|
<entryName>
|
|
{
|
|
type scale;
|
|
|
|
scale
|
|
{
|
|
type linearRamp;
|
|
|
|
start 0;
|
|
duration 10;
|
|
}
|
|
|
|
value
|
|
{
|
|
type sine;
|
|
|
|
frequency 10;
|
|
amplitude 1;
|
|
scale (1 0.1 0);
|
|
level (10 1 0);
|
|
}
|
|
}
|
|
\endverbatim
|
|
|
|
Where:
|
|
\table
|
|
Property | Description | Required
|
|
value | Function of type Function1<Type> | yes
|
|
scale | Scaling function of type Function1<scalar> | yes
|
|
\endtable
