COMSOL 6.3 - Material Libraries

The AC/DC materials library contains a number of materials that assist in modeling electromagnetic components such as actuators, motors, loudspeakers, generators, and so on. Two branches of material, (

) and (

) in the (

), are frequently used. The branch includes typical materials for electromagnetics modeling and the branch includes nonlinear magnetization curves for a large set of ferromagnetic alloys.

	For detailed information about Materials including the AC/DC Material Library and Nonlinear Magnetic Material Library, see the COMSOL Multiphysics Reference Manual.

The folder in the AC/DC Material Library branch contains values for the Thermal conductivity, Electric conductivity, Dynamic viscosity, and Density for liquid Titanium, Steel, Iron, Nickel, Copper, Aluminum, Magnesium, Tin, Lithium, Sodium, Wood’s metal, Potassium, Gallium, NaK (Sodium-potassium eutectic), and Mercury based on the book Introduction to Magnetohydrodynamics by P.A. Davidson, published by Cambridge University Press. Copyright (c) P.A. Davidson 2017. Reproduced with permission of Cambridge University Press through PLSclear.

The folder in the AC/DC Material Library branch contains values for the Electric conductivity, the Relative permittivity, and the Reference temperature, together with the Relaxation times and Relative permittivity contributions of several Debye poles, for 54 biological tissue types. This data can be used together with the Multipole Debye dispersion material models, and is taken from Ref. 1.

The AC/DC Material Library also contains the material property data from the following company’s products:

NdFeB standard grades¹ (–, M, H, SH, UH, EH, AH, BH, /S, M/S, H/S, SH/S, UH/S, EH/S, AH/S, BH/S, H/ST, SH/ST, UH/ST, EH/ST, AH/ST, BH/ST), NdFeB (bonded, injection molded, and extruded), Ferrite (isotropic, anisotropic, and injection molded), SmCo (injection molded), SmFeN (injection molded), SmCo5 grades, Sm2Co17 grades, and AlNiCo (cast and sintered).
