I work on engineering simulation and 3D modeling, mainly in structural mechanics, CFD, heat transfer, electromagnetics, acoustics and biomedical analysis. I use COMSOL Multiphysics, ANSYS, SOLIDWORKS and MATLAB/Simulink. I can work from your own geometry, build a model from scratch, or reproduce results from a published paper. Projects I have completed: ❖ Transformer cooling: modeled a 3500 kVA oil-filled transformer to compare plant-based ester oil (FR3) with standard mineral oil at 75% to 150% load. ❖ Liquid metal droplet control: simulated how a droplet of gallium-based liquid metal moves when a voltage is applied (electrowetting), with the voltage varied from 150 V to 250 V. ❖ Cryogenic cooling: modeled an optical component inside a vacuum chamber cooling from room temperature down to 4 K (-269 °C), including heat lost through radiation. ❖ Thermal stress in a viewing window: calculated the stress in a sapphire window brazed to a metal flange when exposed to extreme cold, to check whether the joint would crack. ❖ Biomedical modeling: studied how a soft gel implant slowly deforms over time inside body tissue, and how sound and vibration travel through knee tissue. ❖ Solar panel fault detection: developed a method to detect electrical faults in solar panel arrays using MATLAB/Simulink. ❖ Motor fault simulation: built a Simulink model of an electric motor that produces data for 24 different fault types, used to train and test fault detection methods. Analysis I can perform: ❖ Stress and deformation, including thermal stress, creep and fatigue ❖ Fluid flow (CFD), including turbulent and two-phase flow ❖ Fluid-structure interaction, where flowing fluid bends or moves a structure ❖ Heat transfer by conduction, convection and radiation, including very low temperatures ❖ Electric fields and electrostatics ❖ RF and sensor modeling ❖ Acoustics and vibration ❖ Biomedical modeling of tissues and implants ❖ Combined physics, such as heat with stress, or electric current with heating With each project you receive the model file, results data, clear plots and a short report explaining the method and findings. Feel free to message me with your problem or paper which you want me to replicate and I will get back to you with my approach and timeline. Regards, Mirza
