Altair FluxMotor 2020.0.1 Release Notes

Fixed issues of FluxMotor 2020.0.1
Two defects in the application "Materials" of FluxMotor 2020 have been fixed.

The characterization of iron loss parameters fails.
This, whatever is the considered process: Either by using one or two referent working points or by using an Excel file where iron losses are defined versus flux density and frequency (ref.: FXM-13010).
Displaying of input labels is wrong
The displaying of inputs is wrong in the dialog box used to define iron loss parameters from two working points (ref.: FXM-13011).

Iron loss model identification - Reminder
Warning: When characterizing the iron loss parameters by using the method with two measurement points there are two things to be known:

1) Firstly, our internal process uses a genetic algorithm to compute the iron loss parameters.
When the same frequency is considered for the two targeted points, this can lead to a disparity on the resulting iron loss parameters. It means that the same set of inputs provide sets of iron loss parameters which can be different. However, the resulting iron loss model give the same total amount of iron losses.
Note: The best way to use the method with two measurement points, is to consider two different frequencies. Thus, there is only one resulting set of iron loss parameters.
2) Secondly, defining the iron loss parameters, with frequency very different from the one which is considered for the computation of a working point in Motor Factory, can lead to wrong results.
The most accurate way to compute iron loss parameters is to use a map of iron losses in f - B plane (f= frequency and B=flux density) where iron losses are defined in function of flux density for different values of frequency. Note that to be accurate the frequency and the flux density of the working point to be computed must be respectively in the range of frequencies and flux densities used to identify the iron loss parameters.
