Sealed Container under pressure

Sealed Container under pressure

Sealed Container under pressure

I am using Cosmos/Works to analyze the deflection of a sealed container in a pressurized environment. In use, the entire container would be slightly "squeezed" towards it's center of gravity. However, Cosmos requires that I contrain some part of the model in order to create a boundary condition to solve the analysis, but doing so is not an accurate representation of what actually happens during loading. I tried the soft-spring setting but it produced junk results. Any suggestion? Thanks!

RE: Sealed Container under pressure

If the geometry is symmetric then model 1/2 or 1/4 of the geometry and use symmetry BCs to constrain the model.

RE: Sealed Container under pressure

Thanks for the suggestion hiyer. Unfortunately, the model is not symmetric.

RE: Sealed Container under pressure

The same question is being asked more appropriately in the finite element forum.   There's no need to ask it twice as your problem is general to all FE models.
