Saltwater intrusion

Hi, I’m a new user of OpenGeoSys and I think this project is pretty interseting.
Actually, I want to simulate about saltwater intrusion(SWI) like Haline Setups or Goswami case but in 3D.
Is it possible to simulate in 3D? And Can I get example files for Haline Setups like Goswami case?
It would be grateful if you reply on this questions. Thanks.
