@DrSOKane , do you have any advice on my approach of applying this to the mohtat dataset/how i can fix this zero porosity cutoff issue? |

It seems that the issue is related to the parameter values. When coupling many degradation effects, the parameters need to be carefully calibrated. This is extremely case dependent, so unfortunately we cannot provide a way to fix that. A way to debug this would be to add one mechanism at a time, and adjust the parameters as you go. |

Hello Pybamm Team -
I have been struggling with trying to perform a coupled degradation analysis on parameter sets that are not OKane2022. My motivation for using different parameter sets is to analyze the degradation performance on battery cells that do not have Si-Ox in the anode. I have tried performing the analysis on the Ai2022, Ecker2015 and Mohtat2020 parameter sets all with different types of error messages. With the Ai2022 and Ecker 2015 parameter sets, I kept getting a solver error and/or Q_p doesn't match Q_Li warning message. With the Mohtat2020 dataset, I get the same warning message and my porosity in the negative electrode goes to 0 very quickly.
Here is my code for the Mohtat2020 parameter set:
Can someone please tell me what is wrong with my approach and how I can correctly/successfully apply this coupled degradation methodology to other parameter sets? @DrSOKane , I would really appreciate your inputs on this.
