OpenFOAM Freelancing Services

High-Fidelity OpenFOAM Consulting & Development

Get precision-engineered CFD solutions from an open-source expert with over a decade of hands-on simulation experience. Whether your team is battling unstable custom solvers or needs immediate, field-ready design optimization, you receive rigorous engineering insight directly applied to your fluid dynamics challenges.

Meet Your CFD Partner: Wiratama

I am Wiratama, a dedicated OpenFOAM freelancer providing elite computational fluid dynamics services to industries worldwide. Since 2013, I have helped engineering teams replace expensive proprietary licenses with tailored, high-performance OpenFOAM workflows. My practice bridges the gap between scientific complexity and commercial reality, ensuring you get accurate data you can confidently base physical manufacturing decisions on.

From Deep Theoretical Frameworks to Field Implementation

My expertise spans the entire spectrum of fluid dynamics complexity. On the theoretical front, I develop custom C++ solver modifications, implement complex boundary conditions, and troubleshoot non-converging turbulence models. I translate advanced academic physics into stable numeric code. On the application front, I pivot seamlessly to design-oriented engineering, optimizing valve geometry, analyzing thermal management in electronics, and predicting aerodynamic behavior for field-ready machinery.

Tailored Services to Advance Your Project

Every simulation project receives custom-tailored execution based on your specific operational bottlenecks. I provide end-to-end CFD pipeline development, including automated high-quality meshing with snappyHexMesh or external tools, custom solver development, and rigorous validation studies. Additionally, I build automated post-processing scripts to give your design engineers clear, actionable visualization data for rapid prototyping cycles.

Why Choose Open Source with Expert Guidance

Deploying OpenFOAM independently often comes with a steep learning curve and frustrating deployment delays. By partnering with an experienced consultant, you bypass the trial-and-error phase entirely. You gain full ownership of your simulation software stack, eliminate recurring per-core licensing fees, and scale your compute workloads infinitely on the cloud, all while maintaining the strict accuracy of verified engineering code.
