Transformer oil electrode configuration model

Hello, I am working on a model involving transformer oil using the following physics interfaces in COMSOL:
Electrostatics - for simulating the electric field. Transport of Diluted Species - to analyze charge movement and density. Heat Transfer - to incorporate the thermal effects in the oil. Despite setting up the physics, I am unable to observe charge density or the progression of charge movement in the oil. I suspect the issue lies in assigning the appropriate parameters, boundary conditions, or coupling mechanisms between the modules.
Could you please assist me in configuring the model correctly? Specifically, I need guidance on:
Defining charge density and its initialization in the Transport of Diluted Species module. Proper coupling between Electrostatics and Transport of Diluted Species for space charge effects. Setting suitable material properties (e.g., permittivity, diffusion coefficients, reaction rates). Any tips for observing charge density changes in the oil. I have attached a picture for reference that I want to model like that. I look forward to your advice and suggestions to resolve this issue.
Best regards,
