How to Easily Connect 1D Pipes to 3D Flow Domains

November 27, 2014

You can easily connect 1D pipes to 3D flow domains for your pipe flow simulations using a feature in the Pipe Flow Module available as of COMSOL Multiphysics® version 5.0.

Multiscale Reactors: Cleaning the Flows

November 3, 2014

Packed bed reactors are used in chemical synthesis and for effluent treatment and catalytic combustion, are often required for heterogeneous catalysis, and commonly include catalyst pellets.

Meshing: Cap off for Cap on

October 11, 2012

Oftentimes when you are working with devices with internal fluid flow, the imported CAD design represents the vessel material. The inside is plainly void. This may leave you clueless since it is inside where you want to create a volume mesh for the flow equations. How can you solve this meshing problem in COMSOL?

Working with CAD

July 3, 2009

This week I will talk about CAD import. Many times, the first task a new user of COMSOL is up to is to lay their hands on the CAD models of the design team. After all, COMSOL handles the analysis, which needs to be closely tied with the design process. Ideally, design and analysis is integrated in one single process. There are different ways to marry the CAD models with the analysis. File based import is maybe the most common […]
