Comparing EIS data of different models in compare_models.py, it appears that the SPMe does not have a semi-circle for the same electrode double-layer capacity as the other models.
options={"surface form": "differential"} and both positive and negative electrode double-layer capacities are set to 0.2 F m-2 for the figure below
This is unexpected as the semi-circles of all models should be quite similar!
Interestingly, semi-circles for the SPMe appear when choosing the electrode double-layer capacity values unreasonably high:
Hi,

100 F/m2:
compared to 0.2 F/m2:
This may be related to the bug in leading surface form conductivity (https://github.com/pybamm-team/PyBaMM/pull/4139), however, using the develop branch does not solve this issue.
We use PyBAMM version 24.1.
Kind regards,
