Modeling a Welding Process with COMSOL Multiphysics®
Länge: 1:00:17
In this archived webinar, learn about using the COMSOL Multiphysics® software to model a welding process.
Dr. Stuart Brown of Veryst Engineering shares how the multiphysics modeling of a valve welding process helped determine the cause of a toxic leak. He demonstrates how to build the model, discusses the toxic leak event, and describes the testing done to verify the simulation.
