Description of the bug

I was using pyaedt v0.6.76 where the method permeability.set_non_linear needed 1 input (a double column nested list).
example: [[0.0, 0.0], [500.0, 0.1], [1000.0, 0.3], [1500.0, 0.4], [2000.0, 0.48], [2500.0, 0.55], [3500.0, 0.6], [5000.0, 0.61], [10000.0, 0.65]] and this was working.

After updating to pyaedt v0.7.3. it is now changed to needing 2 inputs :
B_value = [0.0, 0.1, 0.3, 0.4, 0.48, 0.55, 0.6, 0.61, 0.65]
H_value = [0.0, 500.0, 1000.0, 1500.0, 2000.0, 2500.0, 3500.0, 5000.0, 10000.0]

But although the function mat.permeability.set_non_linear(B_values,H_values) returns True, in ANSYS the material permeability is still set to "Simple" with the value of 1.

Steps To Reproduce

B_value = [0.0, 0.1, 0.3, 0.4, 0.48, 0.55, 0.6, 0.61, 0.65]
H_value = [0.0, 500.0, 1000.0, 1500.0, 2000.0, 2500.0, 3500.0, 5000.0, 10000.0]

mat = M3D.materials.add_material("newMat")
mat.permeability.set_non_linear(B_values,H_values)

Material is not updated with B and H values and still set to "simple".

Hi @SanderBovee ,

This performance of this method changed some versions ago and it evolve in something more pythonic. I have just created a Pull request to make this method private, and then users will not have direct access.

As I said, now is more pythonic and consistent with other material properties, please use this code:

import pyaedt

app = pyaedt.Hfss(specified_version="2023.2")

B_value = [0.0, 0.1, 0.3, 0.4, 0.48, 0.55, 0.6, 0.61, 0.65]
H_value = [0.0, 500.0, 1000.0, 1500.0, 2000.0, 2500.0, 3500.0, 5000.0, 10000.0]

mat = app.materials.add_material("newMat")
b_h_dataset = [[b, h] for b, h in zip(B_value, H_value)]
mat.permeability = b_h_dataset

app.release_desktop()

Hi @Samuelopez-ansys,

Ah, I see. That works indeed. Thank you for the information and for responding so quickly.
