About this gig
Are you looking to optimize your fluid dynamics, heat transfer, or multiphysics design? I provide professional Computational Fluid Dynamics (CFD) simulations using industry-leading software: Simcenter STAR-CCM+, COMSOL Multiphysics, and ANSYS (Fluent/CFX).
From aerodynamics to complex conjugate heat transfer, I deliver deep analytical insights to improve performance and validate your engineering concepts.
Advanced CFD Capabilities:
- Fluid Dynamics: Steady-state, transient, laminar, and turbulent flows (RANS, LES).
- Thermal Management: Conjugate Heat Transfer (CHT), radiation, and electronics cooling.
- Multiphysics & Phase Change: Multiphase flows (VOF), particle tracking (DEM), and chemical reactions.
- Aerodynamics: Lift/drag optimization for automotive, aerospace, and marine systems.
- Rigorous Verification: Mesh independence studies and post-processing with high-resolution contours, plots, and raw data export.
Get reliable, physics-backed data to accelerate your product development cycle.

FAQ
Which CFD software is best for my specific project?
It depends on the physics. ANSYS Fluent is excellent for general aerodynamics and combustion; STAR-CCM+ excels in marine hydrodynamics and large mesh automotive flows; COMSOL is best for coupled multiphysics (e.g., electrochemistry + fluid).
Do you provide a mesh independence study?
Yes, standard engineering practice dictates verifying results. I perform grid convergence tests in the Standard and Premium tiers to eliminate mesh bias.
Can you handle transient (time-dependent) simulations?
Absolutely. I set up accurate time-stepping schemes for vortex shedding, sloshing, and other time-accurate transient phenomena.
What files will I receive upon project completion?
You will receive a comprehensive PDF report containing contours, charts, and data tables. Native simulation files (.sim, .cas/.dat, or .mph) can be provided based on the package selected.
Do you require a clean CAD model?
Ideally, yes. However, I can perform basic geometry cleanup, fluid volume extraction, and defeaturing as an add-on service.
Do you sign non-disclosure agreements (NDAs)?
Yes. I respect intellectual property and am happy to sign an NDA before you share any sensitive proprietary geometry or data.
