Detailed Description

Computes forces and moments over a given list of patches by integrating pressure and viscous forces and moments, and optionally resistance forces and moments from porous zones.

Forces and moments are output in their total and constituent components:

total forces and moments
pressure contributions
viscous contributions
porous resistance contributions (optional)

Forces and moments can be computed and output in:

the global Cartesian coordinate system (default)
a user-defined Cartesian coordinate system

Operands:

Operand	Type	Location
`input`	-	-
`output` file	dat	postProcessing/<FO>/<time>/<file>s
`output` field	volVectorField	<time>/<outField>s

where <file>s:

      force.dat        | Forces
      moment.dat       | Moments

where <outField>s:

      <namePrefix>:force   | Force field
      <namePrefix>:moment  | Moment field

Usage

Minimal example by using system/controlDict.functions:

<namePrefix>
{
    // Mandatory entries
    type                forces;
    libs                (forces);
    patches             (<wordRes>);

    // Optional entries
    directForceDensity  <bool>;
    porosity            <bool>;
    writeFields         <bool>;
    useNamePrefix       <bool>;

    // Conditional mandatory entries

        // if directForceDensity == true
        fD              <word>;


        // Cartesian coordinate system specification when
        // evaluating forces and moments, either of the below

        // Option-1, i.e. the centre of rotation
        // by inherently using e3=(0 0 1) and e1=(1 0 0)
        CofR                (0 0 0); // Centre of rotation

        // Option-2, i.e. local coordinate system specification
        origin              (0 0 0);
        e1                  (1 0 0);
        e3                  (0 0 1); // (e1, e2) or (e2, e3) or (e3, e1)

        // Option-3, i.e. general coordinate system specification
        coordinateSystem
        {
            type            cartesian;
            origin          (0 0 0);
            rotation
            {
                type        axes;
                e3          (0 0 1);
                e1          (1 0 0); // (e1, e2) or (e2, e3) or (e3, e1)
            }
        }

    // Conditional optional entries

        // if directForceDensity == false
        p               <word>;
        U               <word>;
        rho             <word>;
        rhoInf          <scalar>; // enabled if rho=rhoInf
        pRef            <scalar>;

    // Inherited entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`type`	Type name: forces	word	yes	-
`libs`	Library name: forces	word	yes	-
`patches`	Names of operand patches	wordRes	yes	-
`directForceDensity`	Flag to directly supply force density	bool	no	false
`porosity`	Flag to include porosity contributions	bool	no	false
`writeFields`	Flag to write force and moment fields	bool	no	false
`useNamePrefix`	Flag to include prefix for field names	bool	no	false
`CofR`	Centre of rotation	vector	cndtnl	-
`origin`	Origin of coordinate system	vector	cndtnl	-
`e3`	e3 coordinate axis	vector	cndtnl	-
`e1`	e1 coordinate axis	vector	cndtnl	-
`coordinateSystem`	Coordinate system specifier	dictionary	cndtnl	-
`fD`	Name of force density field	word	cndtnl	-
`p`	Name of pressure field	word	cndtnl	p
`U`	Name of velocity field	word	cndtnl	U
`rho`	Name of density field	word	cndtnl	rho
`rhoInf`	Value of reference density	scalar	cndtnl	-
`pRef`	Value of reference pressure	scalar	cndtnl	0

The inherited entries are elaborated in:

Note

For incompressible cases, set rho to rhoInf. You will then be required to provide a rhoInf value corresponding to the constant freestream density.
writeControl and writeInterval entries of function object do control when to output force and moment files and fields.
