Hire the Best FEA simulations Freelancers
in the United States

Hello, Let me introduce myself. I am a physics engineer, materials science, and I have more than 15 years of experience as a design engineer. I have extensive experience in detailed design and modeling of tools and equipment, tolerance, and dimensional analysis. Very proficient in CAD, specifically in SolidWorks (owner of a Premium and Simulation Pro), Fusion 360 experience as well. Selection of materials, production processes, and suppliers. Calculation of cost and production time. I have experience designing finished products and tools/molds for the mold injection process, systems for high vacuum/ high pressure, inert, and dangerous gases, reverse engineering, CFD, and FEA analysis. Customer-oriented - I try to be neutral and objective, I fully listen to the person's comments and reflect on my work at the same time, with this fresh new perspective coming from this person's viewpoint. I respect they took the time to give me feedback and value their opinion. My job as a designer is to identify and find valuable solutions that will better serve customers. Sincerely, Vitaly

I bridge the gap between rigorous engineering physics and fast-paced product development. As a PhD Mechanical Engineer and startup founder, I offer a rare combination of deep theoretical knowledge and practical, hands-on building experience. I don't just design parts in CAD. I engineer complete systems by handling the mechanical design, optical integration, thermal analysis, and the Python code that makes it all run. Whether you need to design a rugged sensor enclosure, automate a testing setup, or model a complex physical system, I bring the "Founder’s Mindset" to your project. I prioritize robust, manufacturable solutions that fit your timeline and budget. My Multi-Disciplinary Expertise: 1. Mechanical Engineering & DFM I take concepts from napkin sketches to mass production. My designs are built for the real world, not just the computer screen. Tools: Expert in SolidWorks and Fusion 360. Capabilities: Design for Manufacturing (CNC, Injection Molding, 3D Printing), GD&T, and complex assembly management. Experience: Engineered high-pressure sensor housings (10,000 psi / 250°C) and solar concentrator modules that survive outdoor elements for 20+ years. 2. Optomechanics & Precision Instrumentation: If your product involves light, lasers, or sensors, I am the specialist you need. I understand how mechanical stress affects optical performance. Experience: Designed and built a sub-micron alignment workstation for fiber-to-chip attachment using high-power CO2 lasers. R&D: Developed novel photonic sensors (published in Seismological Research Letters and Applied Optics), proving my ability to develop and handle extremely sensitive instrumentation. 3. Engineering Computation (Python & FEA) I use code and simulations to validate hardware. I rely on calculation rather than guesswork. Simulation: Advanced Finite Element Analysis (ANSYS/COMSOL) for thermal, structural, ray/wave optics and multiphysics problems. Python: Proficient in NumPy, SciPy, and Pandas for data analysis and physics-based modeling. Automation: I build custom GUIs (Tkinter) to interface with hardware and automate data acquisition. Why Clients Trust Me: I have built my own company: As a founder in the renewable energy sector, I treat your capital with the same respect I treat my own. I focus on viable, scalable engineering. I solve the "Hard" problems: I specialize in projects where standard engineering isn't enough, such as those involving extreme temperatures, high pressures, and sub-micron tolerances. If you need a partner who can see the whole picture, from the mechanical system to the physics inside, click "Invite to Job" and let’s discuss your project.

I have 25 years of experience in applying physics-based methods (such as CFD, FEA, heat transfer, turbulence, mass transfer, bio-reactions, and chemistry), hand calculations, testing techniques, and statistical analysis across diverse industries, including aerospace, medical, semiconductor, apparel, footwear, gloves, automotive, and chemical processing. My expertise spans from concept development to prototype creation and commercial launch, with a focus on scaling processes and equipment from prototype to commercial scale. Many of these product developments are supported and validated by tests conducted in a cost-effective, technically balanced manner. I address significant uncertainties by making well-considered assumptions and approximations, often solving simplified 0D, 1D, 2D, or simplified 3D models with enough physics to guide product development, rather than solving the most complex real 3D geometries. I have worked with tools such as ANSYS Fluent, CFX, STAR-CCM+, CFD-ACE+, TAITherm, OpenFOAM, and ANSYS Mechanical for various applications. Key Contributions: • Collaborated with test and design engineers in developing next-generation engines for launch vehicles and spacecraft, including systems such as thrust chamber cooling, fuel/oxidizer pressurization, fuel tank filling and emptying, manifolds, injectors, diffusers, flow straighteners, and cavity purge analysis, using STAR-CCM+ and ANSYS Fluent. • Supported test campaigns, integrating CFD analysis with hotfire test data and ensuring the digital twin remained up to date. • Led component, subsystem, and product-level simulations to support design, development, verification, and validation efforts, ensuring performance in intended environments and conditions. • Developed thermal analysis models using ANSYS, STAR-CCM+, ACE+, and MSC Patran at various levels, including components, multichip modules, circuit card assemblies, subsystems, and systems, resulting in low thermal-risk hardware. • Created test plans and procedures that led to successful execution and results. • Identified and tested advanced thermal interface materials (TIMs). • Performed thermal analysis model correlations to refine predictions based on test data, enhancing understanding and accuracy. • Worked closely with customers and engineering teams to define the necessary testing to validate thermal analyses and ensure compliance with requirements. • Applied hand calculations and ANSYS Fluent thermal analysis to guide the design of evaporators and cooling plates. • Optimized advanced IC designs to ensure optimal thermal performance. • Utilized aerogel-based insulation composites to mitigate hotspots and meet touch safety requirements. • Conducted thermal analysis for fire testing of building construction and materials.
