Hello Foamers,

I am looking in a pointDisplacement file,

in the file
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);
}
is defined.

I want to check the definitions of omega, axis, origin, angle0, amplitude

so I checked angularOscillatingDisplacementPointPatchVectorFiel d.H and angularOscillatingDisplacementPointPatchVectorFiel d.C

but there were no definitions about them,
they were just declared.

could you please teach me how to find the definition of them?

Regards,

Sungbae Lee

Hi, Sungbae,
Probably it seems obvious, but: omega is the angular frecuency in rad/s, axis is the rotation axis, origin is a point of this axis, angle0 is the angular position in the initial time and amplitude is the amplitude of movement (which I think should be positive...)

Regards

Robert

Thanks Robert,

but I want to know where they are defined with description and equations
