how to place pressures on ribs with opposite directions

Sandra_Dong

I am trying to do a simulation for expansion tank, to save more time I am trying to do it in Hypermesh in 2d of midmesh, after the analysis of the out surfaces I need to add ribs inside but now I realize the problem of adding two opposite directions' pressure seems like impossible, is there a sensible way to do it?

you can define it on the same element in the opposite direction
