Samuel K.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

PhD engineer offering FEA, CFD, and multiphysics simulation for product development and research. I build, debug, and validate models in ANSYS, COMSOL, and LS-DYNA, and I report results clearly enough to go straight into a design review or a journal paper. 🎯 What I do ✔️ Finite element analysis (FEA): structural, dynamic, and impact analysis of parts, frames, and assemblies in ANSYS, SolidWorks Simulation, Abaqus, and LS-DYNA, including crashworthiness of thin-walled and composite structures and underwater explosion (UNDEX) with fluid-structure interaction ✔️ CFD and thermal-fluid analysis in ANSYS and COMSOL: internal and external flow (airflow, ducts, aerodynamics), heat transfer and cooling, and fluid-structure interaction ✔️ Multiphysics in COMSOL: piezoelectric devices and energy harvesters, coupled structural-electrical models ✔️ Particle and granular simulation (DEM): Altair EDEM, PFC2D and PFC3D ✔️ Optimization and data-driven modelling: DOE and response surface methods in Minitab, neural networks and genetic algorithms in MATLAB ✔️ CAD and manufacturing support: SolidWorks parts, assemblies, and drawings; CNC toolpaths in Fusion 360 ✔️ Research writing: manuscripts, theses, and technical reports, backed by peer-reviewed publications 🎯 What you receive ✔️ A model with documented mesh and convergence checks ✔️ Validation against hand calculations, test data, or published results where available ✔️ A clear report with plots and design recommendations, plus the native model and result files 🎯 Background PhD in Manufacturing Engineering, with university teaching experience as an Assistant Professor of Mechanical Engineering. I have hands-on lab experience in powder metallurgy, friction stir processing, heat treatment, tribology, TGA, and XRD, so my models rest on realistic materials and boundary conditions. Send me your geometry, loads, and the decision the results need to support, and I'll tell you what's feasible and how long it will take.
