# Recommendations for Flux 3D

For Flux 3D, the machines used are the following ones:

The machine (a) used for the Magnetostatic and Transient Magnetic applications is the same machine used for the Flux 2D and Flux Skew examples.

The machine (b) used in Steady-State AC magnetic, is the same as for the 2D Flux example seen previously.

Following the simulations, several recommendations are provided in the tables below for each of the 3D Flux applications (Transient Magnetic, Steady-State AC magnetic, and Magnetostatic):
