How to call phase parameter in submodels that are not dorectly related to phase?

[RuiheLi]

Dear PyBaMM,

I find that in the submodels files, like base_sei.py, when we want to call phase parameters, we do

a = self.phase_param.a

However, what if we want to call phase parameters in other submodel like electrolyte diffusion? If we do the same, it will say something like

xxx object has no attribute 'phase_param'

Thanks so much!

There's no concept of phase for the electrolyte submodel. Which parameter are you trying to access?

Thanks for the kind reply!

Quite a few, for example, c_ec_0_dim, and some others which are used in the SEI sub-model.

You can do param.n.prim.c_ec_0_dim for the EC concentration of the primary phase, param.n.sec.c_ec_0_dim for the secondary phase
