Getting the Most out of Client-Server Mode
Learn how to use Client-Server mode when modeling in COMSOL Multiphysics® on a Floating Network License — and see why it is beneficial for you to do so.
How to Integrate Functions Without Knowing the Limits of the Integral
Did you know that the COMSOL® software can solve integrals as well as partial differential equations? Learn how to integrate functions — even without knowing the limits of the integral.
What Kinds of FSI Problems Can COMSOL Multiphysics Solve?
We discuss the various techniques for modeling fluid–structure interaction (FSI) in the COMSOL® software, as well as highlight the add-on modules you need for these various types of analyses.
Modeling the Hydrostatic Pressure of a Fluid in a Deformable Container
Picture a water balloon being compressed at the center. As you squeeze the balloon, the locations of the highest point and depth of fluid change, altering the hydrostatic pressure distribution.
Computing the Impedance of a Corrugated Waveguide
Did you know that you can compute the effective impedance for waveguides with nonuniform cross sections (such as corrugated waveguides) in COMSOL Multiphysics®? We demonstrate how here >>
Optimizing Heater Power for Thermal Processing
We demonstrate a useful approach for process control modeling and optimization using COMSOL Multiphysics® and the Optimization Module.
Implementing a Simple Temperature Controller with a Component Coupling
Learn how to implement a simple temperature controller (a feedback loop) in a thermal process simulation in COMSOL Multiphysics®. We demonstrate with a silicon wafer example >>
Computing and Controlling the Volume of a Cavity
See a method for modeling enclosed volumes containing incompressible fluids (under the additional assumption that the momentum and energy transfer via the fluid is small) in COMSOL Multiphysics®.
