How to Simulate Control Systems Using the PID Controller Add-In
A PID controller can be used in a variety of industries. This blog post demonstrates how a PID controller add-in can be easily incorporated in two simulation examples.
Finding the Best Way to Make Crêpes with Fluid Dynamics Research
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.
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.
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.
Calculating the Heat Transfer Coefficient for Flat and Corrugated Plates
What is the heat transfer coefficient, and how do you calculate it? This blog post includes a theoretical background and demonstration of 2 examples in COMSOL Multiphysics®.
Modeling Fluid-Structure Interaction in Multibody Mechanisms
To model advanced FSI scenarios, such as swimming mechanisms or airflow around a wind turbine blade, you can use the Fluid-Structure Interaction, Pair multiphysics coupling.
