External Material, AC/DC Module, General HB/BH relation

Application ID: 32321


The AC/DC magnetic interfaces now support material models defined in external C code. A new way to specify user-defined material models is included in COMSOL Multiphysics version 5.2. You can now access external material functions, written in C code, which have been compiled into a shared library. By writing a wrapper function in C code, you can also use material functions written in another programming language. This makes it possible to program your own material models and distribute such models as add-ons.

This model is featured and explained in much greater detail in the following blog post: Accessing External Material Models for Magnetic Simulations.

This model example illustrates applications of this type that would nominally be built using the following products:
