Hello,
I am fairly new to comsol, and to start out in the fluid-simulations and fluid-structure-interaction I wanted to model the "swirling" motion of a fluid inside a circularly agitated vessel.
I figured as the structure ist rotationally invariant, I can model this using the 2D axisymmetric component and just model a very basic container with two regions inside. I imported the structural mechanics module, the phasefield module, the laminar flow module and the two-phase-flow interface (multiphysics)
(sry if the names are not 100 % correct, I am using the software in german)
Using this model I should be able to model the flow while swirling by applying a time-dependent volume force. I am however quite puzzled how I should explain the software that the Force vector is rotating (phi-dependent)
can anybody help me?
