paramset: ``` import pybamm import os import numpy as np y_low = 0.18 y_up = 0.819 y_mid = (y_low + y_up) / 2 x_gr_low = 0.053410 x_gr_up = 0.86455 x_gr_mid...

After reading the literature, I wondered if it was due to the current problem. I modified the current calculation method and it seemed to be improved. The following is my...

@ejfdickinson The formula in the Wycisk paper is $\frac{\mathrm{d}h(z,t)}{\mathrm{d}t}=\left(\frac{k(z)\cdot I(t)}{Q_{\mathrm{Cell}}}\right)\left(1-\mathrm{sgn}\left(\frac{\mathrm{d}z(t)}{\mathrm{d}t}\right)h(z,t)\right)$ where $Q_{cell}$ is the capacity of the cell and $𝐼(𝑡)$ is the current. As in pybamm, the current $𝐼(𝑡)$ uses...

Thanks @ejfdickinson , keeping the 24.5 release code and scale the decay rate parameter magnitude has the same effect.

@mleot thanks for reply, I modify the initial condition just for fit the experiment data (cell is fully charged before discharge), but setting initial condition to zero does not make...
