Integration of Geological Structures into Regional-Scale Groundwater Models

November 19, 2019

To study the dynamics of hydraulic processes at different scales, geotechnical researchers need to be able to integrate complex geological structures into their hydrogeological models.

Performing a Shape and Topology Optimization of a Tesla Microvalve

November 15, 2019

1 Tesla microvalve model, 2 ways: The shape optimization features available in COMSOL Multiphysics enable you to improve simple designs inspired by more complex topology optimization results.

Finding the Best Way to Make Crêpes with Fluid Dynamics Research

November 6, 2019

The recipe for the perfect crêpe calls for flour, eggs, milk, sugar, butter, and…simulation? Fluid dynamicists used simulation to solve the optimal coverage problem for crêpe making.

The Importance of Thermal Radiation in Your Models

August 23, 2019

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®

June 19, 2019

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®

June 12, 2019

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®

June 11, 2019

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

May 22, 2019

The discrete ordinates method, P1 approximation, Rosseland approximation, or the Beer–Lambert law: Which should you use to analyze heat transfer in participating media?
