COMSOL 2D Electric Field Simulation

My project involves setting up and running a COMSOL Multiphysics study that calculates electric‐field and voltage distribution for a simple 2-D cross-section. I will supply geometry dimensions, material properties, boundary conditions, and any variable parameters; your task is to build the model, run the study, and extract clear electric, magnetic, or electromagnetic field results—specifically the electric field intensity, equipotential lines, and voltage profiles I need for analysis.

Deliverables
• The native COMSOL (.mph) file with all study steps, mesh settings, and parameter definitions fully documented
• Plots and data tables showing electric field vectors, voltage contours, and any requested derived quantities
• A brief note or screenshot guide that explains how to tweak the key parameters and rerun the simulation

Acceptance criteria
• Field plots visually agree with expected qualitative behavior (I will share reference sketches)
• Numeric results converge under mesh refinement, demonstrated by at least one mesh-independence check
• All units, material values, and boundary conditions match those I provide exactly

No geometry post-processing or 3-D extension is required at this stage; the focus is accurate 2-D field modeling and clear, reproducible output.
