The different working conditions you want to simulate can be done using parametric study in AIM. Following are the steps involved:
1. Promote input and output parameters from your setup. This can be done by clicking on the box named P against any entity that you want to use as parameter. For instance, I have promoted relative permittivity as an input parameter as shown below:
2. Once the parameters are identified, open the design point dash board by clicking the icon (as shown below) on the top right side of AIM window:
3. This will open the design point table. You may define different combinations of input parameters that yo want to simulate and hit "Update all design points" to solve for different magnetic strengths one by one.
Please let me know if you have any further query.
Thanks & Regards,
