With a Lagrangian formulation for fluids, the particle finite element method (PFEM) is ideal for simulating fluid-structure interaction (FSI) with all the solid elements and constitutive models available in OpenSees. The initial applications of the PFEM in OpenSees were simulations of tsunami loading on structures, where the fluid flow was gravity driven or based on … Continue reading Sloshing Around →

The Particle Finite Element Method (PFEM), developed by researchers at CIMNE in Barcelona, is an effective approach for simulating fluid-structure interaction (FSI). Because it is Lagrangian, as opposed to Eulerian, the PFEM is a natural choice for coupling with the structural finite elements in OpenSees. And the coupling is monolithic, i.e., in one system of … Continue reading The PFEM in OpenSees →
