Could you provide an explanation for the "Interface Compression" setting in CFX-Pre - what it is, when it should be used and what the consequent values mean.

Free surface flows use a compressive differencing scheme for the advection of volume fractions to achieve a sharp interface. The Interface Compression level controls which scheme is used. 0 = None This means that a compressive differencing scheme is not used; the normal scheme that is employed for other equations is used. 1 = Standard Compression This is the default compressive differencing scheme. 2 = Enhanced Compression This is a new scheme introduced in CFX-10. It's designed to be more compressive to give a sharper interface. |
