Usage of is_components

[SebGue]

Hello,

could you tell me, what the meaning of is_components property exactly is.

The reasom is, that I had some trouble with this property, i.e. is_components is set to True for indices in MagFEMM\build_meshsolution method (line 33), while I consider indices not to be a component.
Indices_Cell = Data1D(name="indice", values=indices_cell, is_components=True)

With is_components set to False, I was not able to get specific indices 'indice[1, 2, 3,...]' of the fields components with get_alone method on a VectorField (e.g. x component of out.mag.B). It only works when is_components of indices is set True.

Best regards, Sebastian

Hello Sebastian,

is_components is a key used to make sure that the values of the axis are never used in a mathematical operation (e.g. indices of a mesh, "A", "B", "C" for the current phases, etc. must not be interpolated). It is true that the name of this parameter is not very well chosen. Maybe I could rename it as "is_not_numbers"?

I am currently working on many improvements and will release a new version soon. In particular get_along methods will return all axes (e.g. sliced axes will be returned as the single value used for the slice), so that you should be able to get indices even with is_components=False.

Best regards, Hélène

Hello Hélène,

Thank you for your explanation. I think you should not rename this parameter, but add your explanation to the class property description and to the tutorial nr. 1 would be helpful.

BR, Sebastian
