Defining a Nonlinear BH Curve Using Ansys Maxwell
Ғылым және технология
This video explains how to define a nonlinear BH curve in Ansys Maxwell as well as introduces when and why a nonlinear BH curve need to be defined. You will also learn how to import BH data into the material definition window and how to add temperature dependent BH curve data for various temperatures. This video also emphasizes on the key points to remember while defining the nonlinear BH curve. For free courses offered through Ansys Innovation Courses visit www.ansys.com/courses.

this video was helpful for my project. thank you
Can you say in 2017a ansys maxwell how I would create temperature dependent BH curve
From where you get the BH dataset?? Is it available in ansys folder or we download from other website??

It's going to be very material dependent, and will likely have to be obtained from either the manufacturer, or through direct testing methods yourself. Ferrites and other magnetic materials tend to be one of those things that aren't super consistent even among like materials, due to often relying on minute details in how the material is processed. Even slight temperature variations during the smelting process can introduce variability in the magnetic subdomains of the material, leading to slightly different behavior, so it'll have to be a bit of a case by case basis when defining the BH curve. Of course, for some common materials, there may be data available for generally expected values, but be forewarned that it could lead to inaccuracies in your own simulation when working with your own final materials.
