Hire the Best Simulation Freelancers
in Pakistan

I have collaborated on advanced technical projects requiring rigorous engineering analysis and high-fidelity modeling. My role involves transforming complex mechanical concepts into optimized, manufacture-ready 3D CAD models and validating them through advanced simulation to ensure zero real-world failures. Some of My Key Achievements & Technical Benchmarks: ✅ CFD Isentropic Validation: Achieved an ultra-precise ~0.36% error rate against theoretical models in supersonic convergent-divergent nozzle simulations. ✅ High-Load Structural Design: Successfully validated complex geometries (like crane hooks and cantilever beams) under extreme structural loads up to 49,000+ N. ✅ Advanced Academic & Lab Rigor: Deep practical experience blending empirical hand calculations with high-end computational solvers. As a freelance Mechanical Engineer and Simulation Specialist, I bring hands-on experience in Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and 3D CAD Modeling. I have successfully delivered data-driven engineering solutions that require meticulous Structural Analysis, Fluid Flow Simulation, and Engineering Design optimization. I specialize in ANSYS and SolidWorks, bridging the gap between raw 3D design and high-level predictive engineering. Whether it is performing a static structural analysis on load-bearing components using Ashby indices for material selection or setting up density-based solvers for complex fluid dynamics, I ensure your designs are safe, efficient, and cost-effective before they ever hit production. ⭐ Why Choose Me Over Others ⭐ ∘ Verified Analytical Accuracy: I don’t just run simulations; I validate them. By coupling ANSYS results with classic engineering hand calculations (like Winkler-Bach curved beam theory), I guarantee data integrity. ∘ Convergence & Mesh Optimization: Specialized in setting up stable, high-quality meshes and turbulence models (k-omega SST) to avoid the "garbage in, garbage out" simulation trap. ∘ Design for Manufacturability (DFM): Because I am fluent in both SolidWorks and simulation, I modify designs in real-time to solve stress concentrations or flow restrictions. ∘ Clear Technical Reporting: You won't just get colorful plots. You will receive comprehensive engineering insights, safety factors, and actionable design recommendations. ∘ Prompt Responsiveness & Collaboration: Transparent communication throughout the simulation loop to ensure your project alignment. ⭐ Services I Provide ⭐ ∘ Advanced 3D CAD Modeling & Design: Creating precise, fully parameterized parts and assemblies in SolidWorks from sketches, concepts, or GrabCAD baselines. ∘ Finite Element Analysis (FEA): Static structural, stress, total deformation, fatigue, and material optimization analysis in ANSYS Mechanical. ∘ Computational Fluid Dynamics (CFD): Flow simulation, pressure drop analysis, velocity profiles, and thermal management using ANSYS Fluent. ∘ Engineering Design Consultation: Reviewing existing designs to identify structural weak points or aerodynamic inefficiencies, minimizing prototyping costs. ∘ 2D Technical Drawings & Layouts: Generating clean, production-ready 2D CAD drawings derived directly from validated 3D models. I look forward to bringing your engineering concepts to life with technical precision, mathematical accuracy, and robust simulation. Let’s build something flawless together!
