how I can use two model type (STRU_PE & FLUSTR_PE) simultaneity?

Dear everyone
I'm modeling liquefaction in backfill of a sheet Quay wall. When I use " structural-plane strain" model type, the "flow" option is disappeared  in the " view property manager property " icon ,so I can't model sea water; and while I use "fluid-structure interaction" model type , the "static nonlinearity"  icon is lost so I can't use soil material.
I use Diana 9.1
How can use two model type ( STRU_PE  &  FLUSTR_PE) simultaneity?
