O'Kane OCV curve noise

[Johannes-hub22]

Hi all,

I am running a basic sim on the O'Kane dataset and do not know why there is some noise on the charge/discharge curve. This is not present in the Chen2020 dataset. I have tried refining the mesh but still no success .

I am trying to derive the IC-DV curve and this noise is amplified. Any advice on reducing the noise would be appreciated.

Thanks in advance for the help.
