Half-cell Model with PSD

[CaXYZ]

Hi all,

I would like to use a DFN-half-cell model with particle size distribution in the working electrode. As a reference I used the example for DFN with particle size distribution

So, my model setup reads:
model_options={'working electrode':'positive','particle size': 'distribution'} model=pybamm.lithium_ion.DFN(options=model_options)

However, when running the code, an error message is printed:
KeyError: "'Negative minimum particle radius [m]' not found. Best matches are ['Positive minimum particle radius [m]', 'Positive maximum particle radius [m]', 'Positive particle radius [m]']"

I then tested adding parameters of a pseudo-particle size distribution for the negative electrode (i.e. PSD parameters of the positive electrode are also used for the negative electrode) but the model still not runs. The following error is shown:

KeyError: "Points not given for a variable in domain 'negative particle size'"

So, is there a way to run DFN-half cell model with particle size distribution in the working electrode?

With best regards
Carsten
