Detailed Description

template<class Type>
class Foam::fv::SemiImplicitSource< Type >

Applies semi-implicit source within a specified region for Type, where <Type>=Scalar/Vector/SphericalTensor/SymmTensor/Tensor. The source rate coefficients are specified as pairs of Su-Sp coefficients, i.e.:

$\‍[ S(x) = S_u + S_p x \‍]$

where

	=	net source for field 'x'
	=	explicit source contribution
	=	linearised implicit contribution

Usage

Minimal example by using constant/fvOptions:

<Type>SemiImplicitSource1
{
    // Mandatory entries (unmodifiable)
    type                <Type>SemiImplicitSource;

    // Mandatory entries (runtime modifiable)
    volumeMode          <volumeModeType>;

    // Specification of sources (OpenFOAM-2206 and newer)
    sources
    {
        // Specified as explicit(Su)/implicit(Sp) tuple:
        k           (30.7 0);
        epsilon     (1.5  0);

        // Specified as Function1 or exprField
        k
        {
            // Time-ramp from 0 to 30.7 at time 5
            explicit table ((0 0) (5 30.7));
            implicit none;
        }
        epsilon
        {
            explicit
            {
                type        exprField:
                expression  "(mag(pos()) < 0.1) ? 1.5 : 0";
            }
        }
    }

    // Traditional specification of sources (OpenFOAM-2112 and older)
    injectionRateSuSp
    {
        // Specified as explicit(Su)/implicit(Sp) tuple:
        k           (30.7 0);
        epsilon     (1.5  0);

        // Specified as Function1
        k
        {
            // Time-ramp from 0 to 30.7 at time 5
            Su  table ((0 0) (5 30.7));
            Sp  0;
        }
        epsilon
        {
            Su  1.5;
            Sp  0;
        }
    }

    // Mandatory/Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: <Type>SemiImplicitSource	word	yes	-
`volumeMode`	Volume mode type	word	yes	-
`sources`	Explicit/implicit sources	dict	cndtnl	-
`injectionRateSuSp`	Explicit/implicit sources	dict	cndtnl	-

The inherited entries are elaborated in:

Options for the volumeMode entry:

      absolute  | Values are given as \<quantity\>
      specific  | Values are given as \<quantity\>/m3

Note: Missing explicit/implicit, Su/Sp entries are equivalent to constant values of zero. However, at one entry must be supplied for the source terms.; To use the exprField (expression fields) handling, the sources dictionary form must be used.
