The goal is to describe how to find Jiles-Atherton coefficients from experimental measurements in order to use it in the new hysteresis material model in Flux 12.1.

Requirements
A dedicated interface has been generated under Matlab software in order to find easily JilesAtherthon coefficients from experimental B-H static cycles measured. To start the application:
1 | Install “MCR_R2015a_win64_installer.exe”. This is done one time for a machine under Windows 64 |
---|---|
2 | Open “Find_Jiles_Atherton_Coefficients.exe” by a double click. The following interface appears: |
To use the application:
1 | Import of B-H curves measured by an experimental way |
---|---|
2 | Fit B-measured with the B-simulated which is used in the optimization algorithm |
3 | Run the genetic algorithm |
4 | Play with parameters by hand (optional step) |
