Possible error when simulating motors of the same design in different FluxMotor versions

When simulating identical machines in different versions, I get different results (reports attached). Do you have an explanation for this or have I made a mistake in the calculation?

    Hi Ann-Sophie

    We have analysed the FluxMotor results in 2020 and in 2021. The difference in the results is coming from an issue of the version 2020.1, so the correct results are those from the versions 2019 and 2021.

    This issue concern, the orientation of the magnet and appear only with part created by the user, and more specifically when the coordinate system of polarization of the magnet is defined with cylindrical coordinates and that several terms was used in the angular coordinate formula.

    So in your case please use the last version of FluxMotor (2021).

    Best regards.
