One of the simplest examples of fluid-structure interaction is hydrostatic loading on a beam, an analysis the PFEM in OpenSees should be able to handle. Suppose the right wall of the tank shown below is a 1.25 cm (1/2 inch) thick steel plate, which we can model with beam elements in two dimensions. The left … Continue reading Hydrostatic Loading on a Wall →

You're not going to conquer incremental dynamic analysis of 3D reinforced concrete frame models the first day you use OpenSees. Some try, but they all fail. Those who start with simple test cases and level up in complexity will succeed. The same goes for fluid-structure interaction. You will not conquer tsunami loading on structures the … Continue reading Just Fillin’ Up the Tank →
