For example the sinusoidal motion of the floating object in the
potentialFreeSurfaceFoam/oscillatingBox tutorial is now specified thus
floatingObject
{
type fixedNormalInletOutletVelocity;
fixTangentialInflow false;
normalVelocity
{
type uniformFixedValue;
uniformValue sine;
uniformValueCoeffs
{
frequency 1;
amplitude table
(
( 0 0)
( 10 0.025)
(1000 0.025)
);
scale (0 1 0);
level (0 0 0);
}
}
value uniform (0 0 0);
}
rather than using
floatingObject
{
type fixedNormalInletOutletVelocity;
fixTangentialInflow false;
normalVelocity
{
type oscillatingFixedValue;
refValue uniform (0 1 0);
offset (0 -1 0);
amplitude table
(
( 0 0)
( 10 0.025)
(1000 0.025)
);
frequency constant 1;
}
value uniform (0 0 0);
}
