Tips for Using the Wall Distance Interface
The Wall Distance interface is used to calculate the distance to a wall in the turbulent flow interfaces available in COMSOL Multiphysics. It can be combined with any other interface and comes in handy when we need to calculate the distance to the nearest wall or detect, as part of a dynamic model, when a moving object will hit a wall. Today, we will study how the Wall Distance interface works and how other interfaces can benefit from its capabilities.
Analyze your Simulation Results with Projection Operators
Have you ever used your hands to make shadow puppets on the wall? By shining a light behind your (three-dimensional) hands, you create two-dimensional projections on the wall. When analyzing your simulation data in COMSOL Multiphysics, you can do something similar with your model using projection operators.
