Simulating a Closing Gate Valve Part 1
Duration: 13:18  

This tutorial shows step-by-step how to simulate a 3D gate valve which closes completely and redirects pipe flow to a different branch in a Y-fitting. We utilize COMSOL's ability to handle very nonlinear materials (in this case fluid viscosity) to emulate the gate itself and thus avoid the numerical issues posed by the actual closing of the valve itself (the topology changes!)
