Greetings! Here's another COMSOL Tips & Tricks to consider... just before the COMSOL Conference next week. We hope to see you there!
COMSOL Multiphysics has many powerful "built-in"
capabilities. Recently, we learned how to use one particular set of features that have turned out to be very useful and practical. Sometimes it is desirable to calculate the average of an expression over a specified shape surrounding a location. COMSOL Multiphysics has a set of built-in operators that do just this using a sphere in 3D or a circle in 2D. The user must specify the radius of the sphere or circle as well as
the expression and the resolution of the operation. For example,
