This example problem demonstrates how to model a fluid that is fully enclosed by a solid (the container). The problem shows how loading on the container, and the resulting container deformation, affect the pressure, volume, density and mass of the contained fluid.
The following features and capabilities are highlighted:
Modeling hydrostatic fluid elements with negative and positive volumes
Use of a gas material model
Reinforcing
A transient analysis of an inflated and rolling tire shows the tire deformation through various load steps.
