Exporting Meshes and Solutions Using the Application Builder

April 6, 2016

You can easily export mesh and analysis data from COMSOL Multiphysics® into a text file. How? Using the Application Builder. We show you how here.

Modeling Thermal Ablation for Material Removal

March 30, 2016

When certain materials are heated to a certain point, they go directly from the solid to the gas phase in a process called ablation. Learn how to model the thermal ablation process here.

Thermal Modeling of Phase-Change Materials with Hysteresis

March 24, 2016

Hysteresis occurs when the melting temperature of a material is different from the solidification temperature. We demonstrate the thermal modeling of such a material here.

How to Choose Between Boundary Conditions for Coil Modeling

March 22, 2016

3 approaches for truncating a domain when modeling an EM coil in free space: the Magnetic Insulation and Perfect Magnetic Conductor boundary conditions as well as the infinite element domain.

Modeling the Thermal Curing Process

March 16, 2016

Polymerization of a thermoset resin is one example of thermal curing, a process in which temperature-induced chemical change occurs in a material.

Using Radial Basis Functions for Surface Interpolation

March 8, 2016

Did you know that you can easily calculate the interpolation between a set of points using a simulation app? Learn more here and download a demo app for design inspiration.

Modeling Coils in the AC/DC Module

March 3, 2016

A key concept when it comes to coil modeling is closing the current loop. Learn how to do so when modeling coils using the AC/DC Module and COMSOL Multiphysics®.

Automate Model Preprocessing with the Application Builder

March 2, 2016

Ever wish you could automate your model preprocessing tasks? In this blog post, we demonstrate how you can use the Application Builder to quickly convert a text input file into a COMSOL model.
