Detailed Description

template<class Type>
class Foam::Function1Types::Square< Type >

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

$a square(f (t - t_0)) s + l$

where

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

=	Description	Data type	Default
=	Amplitude	Function1<scalar>
=	Frequency [1/s]	Function1<scalar>
=	Type scale factor	Function1<Type>
=	Type offset level	Function1<Type>
=	Start time [s]	scalar	0
=	mark/space ratio	scalar	1
=	Time [s]	scalar

Example for a scalar:

        <entryName> square;
        <entryName>Coeffs
        {
            frequency 10;
            amplitude 0.1;
            scale     2e-6;
            level     2e-6;
        }

Example for a vector:

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