I need a clean, well-documented COMSOL model that captures the fully coupled electro-mechanical response of a piezoelectric polymer structure. The goal is straightforward: simulate and analyse how the chosen polymer behaves when mechanical stress and electrical fields interact, then extract the key performance metrics (voltages, stresses, strains, charge density, etc.) across the domain. The work starts with choosing or inputting the correct piezoelectric material constants, building or importing the geometry, and applying boundary conditions that reflect a realistic operating scenario. From there, the study should solve the coupled governing equations, followed by post-processing that isolates the most insightful plots and numerical results—field distributions, mode shapes, impedan...

roject Description I am currently working on a Master’s thesis project focused on the aerodynamic performance of axial fans.
