Hello Sayem, there are several things you need to check in order to fix this error. A few things to check
1 On the 2nd page of the Machine Toolkit UI, please modify the "Number of speed points" and "Number of torque points" to large integer values like 40.
2 Please check the "Core Loss Setting". In the Machine Toolkit, if the option "separate stator and rotor core losses" is enabled, then the user needs to make sure there is at least one component of stator and rotor with core loss calculation activated.
If none of the above helps, please create a Support Case so that we can further investigate the issue.
