Hello,
I am trying to simulate a lithium-ion battery with multiple intercalating cathode materials. I am using NMC 811 and LFP as the cathode materials in this model. I have followed the procedure as it is described in the COMSOL documentation: Lithium-ion battery with multiple intercalating electrode materials. The main difference is in the material I have used.
The figure below shows the "model builder" of my model:
I would be pleased to share the mph file if anyone could possibly sort this out.
The following is the displayed error upon solving:
