Hi,
Does anybody know why the atmospheric BC for U in the DTCHull-tutorial

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

does not include the line

tangentialVelocity $internalField;

?

To me it seems like we, in the case of inflow at the atmosphere, have a boat the moves relative to the air and water, and then we have an atmosphere that moves with the same speed as the boat.
