Engineers at BE CAE & Test (Catania, Italy) have taken the simulation process well beyond the typical approach of “run a test / deliver a report.” Instead, using the COMSOL Multiphysics software and the Application Builder, they have created a series of easy-to-use custom applications that perform state-of-the-art virtual prototyping of their customers’ surface-mount device designs. The apps hide the complexity of the underlying detailed model, yet still provide access to the powerful functionality of the simulation.
