This example demonstrates how to set up the classical external-flow problem of solving for the high-speed, compressible, turbulent flow over the ONERA-M6 wing. The problem involves finding a steady-state solution of the flow field around the 3D, swept wing geometry, immersed in a ... En savoir plus
This model tracks a contaminant that enters an aquifer at a point, such as an injection well or toxic spill, and spreads through the aquifer with time. The model has an analytic solution developed by Wilson and Miller. This analytic solution has been used to test several dedicated fluid ... En savoir plus
These two apps can be run to set up a digital twin of an electric scooter battery. The Digital Twin Simulator of an Electric Scooter Battery (the "simulator" app) simulates the use of an electric scooter and generates battery current and voltage data over time. The Digital Twin ... En savoir plus
This is a model of a moving-coil loudspeaker where a lumped parameter analogy represents the behavior of the electrical and mechanical speaker components. The Thiele-Small parameters (small-signal parameters) serve as input to the lumped model, which is represented by an Electric Circuit ... En savoir plus
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... En savoir plus
