The user must choose between entering the orifice coefficient or the element endpoint pressure PELEW (See element card (3,2)) for any element for which the outlet does not interface with a compressible volume. Usually, the pressure is much more readily available to use as input data; however, there may be cases in which a user wishes to enter orifice coefficients instead, and so this option has been made available at this point.).
