Flip direction of hydrostatic pressure?

Ishmael

I'm very pleased with Mecway so far and this seems like something obvious I must be missing, yet I've been unable to find anything using various search tools.

Is there a way to flip the direction of a hydrostatic pressure applied to shell elements? I tried selecting the opposite face when defining the named selection to which the load is applied, but it didn't appear to have any effect. In the attached image of a drum filled with liquid, I need the pressures to point outward, instead of inward.

Answering my own question, it turns out that indeed a selection set of FACES -- not elements -- may be used to define a named selection, to which a hydrostatic pressure may be applied in the expected direction.
