Vaccum Simulation

Hi! 

I need help doing one simulation study.

 

I want to simulate what happens to, for example, an coke can when its subject to full vaccum inside.

 

So, what i normally would do its do apply yo the inner faces of the solid one pressure to the inside of +/- 0.1MPa (equivalent to almost full vaccu force [1kg/cm2]).

 

Until tis point its easy, my problem is what face do I select as fixed. Nothing is fixed when full vaccum is applied, the can is just standing on the table and it can compress in all directions. But if i don't select any face as fixed Inventor does no alow me to simulate. 

 

any help on this?
