Hello folks,

I am using openfoam 5 and looking at a flap-type wavemaker case.

in the pointDisplacement file,

FoamFile
{
version 2.0;
format ascii;
class pointVectorField;
location "0";
object pointDisplacement;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
dimensions [0 1 0 0 0 0 0];

internalField uniform (0 0 0);

boundaryField
{
//- Set patchGroups for constraint patches
#includeEtc "caseDicts/setConstraintTypes"

inlet
{
type fixedValue;
value uniform (0 0 0);
}

outlet
{
type fixedValue;
value uniform (0 0 0);
}

bottom
{
type fixedValue;
value uniform (0 0 0);
}

atmosphere
{
type fixedValue;
value uniform (0 0 0);
}

flapper
{
type angularOscillatingDisplacement;
omega 2.86; // 2.2 second period
axis (0 0 1);
origin (3.1 -2.44 0.05);
angle0 0;
amplitude -0.048; // Max piston stroke
value uniform (0 0 0);
}
}

Where and how can I find how flapper is defined?

could anyone tell me?

and could anyone tell me how to look up openfoam source code?

An example could be very useful to me.

Thank you.

Hi,

you should look for the angularOscillatingDisplacement boundary condition in the source

src/code.fvMotionSolver/pointPatchFields/derived/angularOscillatingDisplacement/angularOscillatingDisplacementPointPatchVectorFiel d.H

Nevertheless you might find this useful:

The source code and tutorial case are online.

Best,
