Detailed Description

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

A templated cosine function, with support for offset etc.

The wave period can be specified directly

$\‍[ a cos(2 \pi (t - t0) / p)) s + l \‍]$

Or it can be specified by the frequency

$\‍[ a cos(2 \pi f (t - t0)) s + l \‍]$

where

=	Description	Units
=	Amplitude	-
=	Frequency	[1/s]
=	Period	[s]
=	Type scale factor	-
=	Type offset level	-
=	Time	[s]
=	Start time offset	[s]

The dictionary specification would typically resemble this:

    entry1
    {
        type        cosine;
        frequency   10;
        amplitude   0.1;

        // A scalar Function1
        scale       2e-6;
        level       2e-6;
    }
    entry2
    {
        type        cosine;
        frequency   10;

        // A vector Function1
        scale       (1 0.1 0);
        level       (10 1 0);
    }

where the entries mean:

Property	Description	Type	Reqd	Default
`type`	Function type: cosine	word	yes
`amplitude`	Amplitude	Function1<scalar>	no	1
`frequency`	Frequency [1/s]	Function1<scalar>	or period
`period`	Period [s]	Function1<scalar>	or frequency
`scale`	Scale factor (Type)	Function1<Type>	yes
`level`	Offset level (Type)	Function1<Type>	yes
`t0`	Start time offset	scalar	no	0

Note: For slow oscillations it can be more intuitive to specify the period.
