Modeling Thermal Ablation for Material Removal
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
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
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
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
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
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®.
Generate Models from Text Files with the Application Builder
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.
Control Current and Voltage Sources with the AC/DC Module
Did you know that you can use the Terminal boundary condition to dynamically switch between excitation types during a transient simulation? This is useful for modeling power supply, for example.
