Simulating soft ground

Hi,

Can anyone advise me in the right direction please? I am fairly experienced within FEA however I have managed to avoid virtual walls for some time which is my area of weakness.

I am attempting to simulate an item being loaded on top of a "soft floor". What would eb the best way to aproach this? Could I use a flexible virtual wall. Where would be the best location to find values for the floor, etc.

Thank you in advance,

Phil.
