Building a Beowulf Cluster for Faster Multiphysics Simulations
In 1994, NASA researchers built a small cluster of normal workstations. They called this parallel workstation Beowulf. Today, “Beowulf cluster” describes clusters built from normal workstations.
Chemical Parameter Estimation Using COMSOL Multiphysics
In this installment of our blog series on chemical kinetics, we discuss how to estimate the chemical parameters of your model in COMSOL Multiphysics®.
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.
Optimizing Mach-Zehnder Modulator Designs with COMSOL Software
3 design requirements for a Mach–Zehnder modulator: It must produce low loss, give a 50/50 split of power through the 2 output arms, and be used as a spatial switch. See how simulation can help.
Characterizing the Flow and Choosing the Right Interface
No matter the focus of your modeling project, you have probably had to consider fluid flow at some point. Here, we discuss how to characterize the flow and choose the correct CFD interface.
