Multiphysics Simulation & Control Systems
Mechanical engineering student learning to model a physical system, simulate how it behaves, and design the control that governs it. I work with ANSYS, MATLAB / Simulink, SolidWorks and Python, and I'm building up multiphysics work in COMSOL. This portfolio documents each simulation project as it's built.
Areas of focus
Model it. Simulate it. Control it.
The portfolio is organised around the complete engineering chain, from a physical system to a controlled, validated response. CAD supports that work; it isn't the headline.
01
Multiphysics Simulation
Coupled thermal, fluid and structural models of real systems.
02
Control Systems
Plant models, feedback design, stability and controlled response.
03
FEA
Stress, deformation and thermal analysis with hand-calculation checks.
04
CFD
Internal and external flow, velocity fields and heat transfer.
05
Dynamic System Modelling
ODE, transfer-function and state-space models of physical systems.
06
Numerical Methods
Discretisation, solvers and convergence for ODE / PDE problems.
Technical workflow
From physical system to validated controller
- Physical SystemGeometry, materials, loads and operating conditions.
- Mathematical ModelGoverning equations, assumptions, boundary and initial conditions.
- Numerical SimulationMesh, solver and physics set-up in ANSYS, MATLAB or Python.
- Engineering AnalysisPlots and contours interpreted physically, not just reported.
- Control / OptimizationControllers and parameter studies built on the model.
- ValidationChecks against theory, hand calculations or measurements.

This portfolio shows work done as a student and is not a claim of professional experience. It documents a developing practice: modelling physical systems, simulating them, and designing the controllers that act on them.
