Useful Tools for Postprocessing in COMSOL Multiphysics
Layering plots; style inheritance; enabling and disabling grids, axes, and legends; showing mesh plots, and more: We go over some useful tools for postprocessing your simulation results.
Using the Boussinesq Approximation for Natural Convection
Today, we compare the Boussinesq approximation to the full Navier-Stokes equations for a natural convection problem. We also show you how to implement the Boussinesq approximation in COMSOL Multiphysics software and discuss potential benefits of doing so.
Studying the Airflow Over a Car Using an Ahmed Body
The Ahmed body is a benchmark model widely used in the automotive industry for validating simulation tools. We discuss simulating airflow over an Ahmed body to optimize automotive aerodynamics.
Predicting Cavitation in Journal Bearings
When designing journal bearings for use in a rotating shaft, the effect of cavitation needs to be considered, because it can affect the performance of these components.
Dielectrophoretic Separation
Dielectrophoresis is a phenomenon in which an electric field is used to control the movement of electrically neutral particles. Learn about how to model this effect in both DC and AC fields.
Geometry Modeling in Simulation Apps
See how to use cumulative selections and geometry parts when creating simulation apps that can be used to model geometries based on parameterized CAD models.
Visualizing Fluid Flow with Streamline Plots
As part of our blog series on postprocessing, we demonstrate the use of streamlines to visually describe fluid flow in your simulations. Learn how with an example of flow through a pipe elbow.
Using Virtual Operations to Simplify Your Geometry
CAD geometry: A set of data structures that provide a very precise method for describing the shapes of parts (called boundary representation, or B-rep).
