Detailed Description

template<class Type>
class Foam::Function1s::Square< Type >

Templated square-wave function with support for an offset level.

\[ a square(f (x - x_0) ) + l \]

where

$square(x)$ is the square-wave function in range $[-1, 1]$ with a mark/space ratio of $r$

$ Symbol $ = Description Data type Default
$ a $ = Amplitude Function1<Type>
$ f $ = Frequency scalar
$ x_0 $ = Phase scalar 0
$ l $ = Offset level Function1<Type>
$ r $ = Mark/space ratio scalar 1

Example for a scalar:

        <entryName> square;
        <entryName>Coeffs
        {
            amplitude 2e-7;
            frequency 10;
            start     0;
            level     2e-6;
            markSpace 0.5;
        }

Example for a vector:

        <entryName> square;
        <entryName>Coeffs
        {
            amplitude (1 0.1 0);
            frequency 10;
            start     0;
            level     (10 1 0);
            markSpace 0.5;
        }
