The Importance of Thermal Radiation in Your Models
Conduction and convection tend to get more attention from simulation engineers, but radiation plays an important role as well. Learn how (and why) to account for thermal radiation in your models.
Building a Magnetohydrodynamic Multiphysics Model in COMSOL®
Magnetohydrodynamic models call for fluid dynamics and electromagnetics couplings. To do so, you can set up bidirectional couplings between all physics equations or building a simplified model.
Introduction to Modeling Acoustic-Structure Interactions in COMSOL®
To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.
Optimizing PID Controller Performance with COMSOL Multiphysics®
PID controllers involve three components that must work together simultaneously, and it can be challenging to get each of them just right. That’s where process control simulation comes in.
4 Methods to Account for Radiation in Participating Media
The discrete ordinates method, P1 approximation, Rosseland approximation, or the Beer–Lambert law: Which should you use to analyze heat transfer in participating media?
Speeding Up DNA Separation in a Microchannel via Simulation
DNA separation takes a long time using traditional methods. Now, researchers from the Missouri University of Science and Technology have found a faster way to get the job done.
Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method
Here’s your complete guide to the discrete ordinates method, quadrature sets, and how to model the interaction between radiation and a participating or absorbing medium.
Comparing Optimization Methods for a Heat Sink Design for 3D Printing
When designing a heat sink, is it better to use parametric or topology optimization? When manufacturing said design, does 3D printing produce the best result, or a conventional method?
