Handling of self-defined materials

[nikmarlo]

Hi,

I am trying to simulate with a self-defined material I have saved as an .amat file (Only containing this single material). Working manually in Maxwell it directly shows up in the material list as

Here is a more detailed view on the material properties.

I used the automatic calculation of the core loss properties, so the original dataset is also saved in the .amat:

If I try to create a box of my self-defined material by
maxwell_3d.modeler.create_box([x_ferr,l_wind+d_wc,z_ferr],[l_core,w_core_a,h_core],name="rightleg",material="Fair-Rite_67")

I get this messages:

PyAEDT ERROR: Method arguments: 
PyAEDT ERROR:     matname = Fair-Rite_67 
PyAEDT ERROR: **************************************************************
PyAEDT WARNING: Material Fair-Rite_67 does not exists. Assigning default material
PyAEDT ERROR: **************************************************************

So I assumed I have to import the material data first. But if I do:
maxwell_3d.materials.import_materials_from_file(r"C:\...\Ansoft\PersonalLib\Ferrite_Materials.amat")

I get the following bunch of PyAEDT Errors:

I started to try out a few things like
maxwell_3d.materials.mat_names_aedt

which gives me a list of about 5700 materials also containing Fair-Rite_67. But if I try to check if the material exists by
maxwell_3d.materials.exists_material('Fair-Rite_67')

I also get Errors instead of just false:

So now I'm a little at a loss as to how to deal with the problem. Thanks in Advance :)

@nikmarlo ,

Have you looked into these examples:

• https://examples.aedt.docs.pyansys.com/version/dev/examples/low_frequency/motor/aedt_motor/pm_synchronous.html#Define-path-for-non-linear-material-properties
• https://examples.aedt.docs.pyansys.com/version/dev/examples/low_frequency/motor/aedt_motor/pm_synchronous.html#Define-path-for-non-linear-material-properties

Not sure if you can add multiple curves, but maybe this helps? Let us know.

@nikmarlo ,

Would this work for you https://aedt.docs.pyansys.com/version/stable/API/_autosummary/ansys.aedt.core.modules.material.Material.set_coreloss_at_frequency.html
