Unlocking Engineering Potential: Insights from the “Power of Open Source CFD” Live Session
Recently, the engineering community was treated to an insightful live session on YouTube titled “The Power of Open Source CFD in Engineering,” featuring esteemed guests Dr. Henry Weller and Dr. Jenya Collings from CFD Direct, the driving force behind OpenFOAM®, alongside Jousef Murad from cloudHPC. This discussion delved deep into the transformative impact of open-source Computational Fluid Dynamics (CFD), particularly OpenFOAM, and how accessible High-Performance Computing (HPC) is amplifying its reach.
If you missed it, don’t worry! We’ve distilled the core takeaways for you. (And you can always watch the full replay here).
The Genesis & Philosophy of OpenFOAM: More Than Just Software
Dr. Henry Weller, one of the original creators of OpenFOAM, shared fascinating insights into its origins. Born from a need for a flexible, extensible, and transparent simulation tool, OpenFOAM was designed from the ground up using C++ for its object-oriented capabilities. This allows it to be a “toolkit” rather than a “black box.”
Key Philosophical Points:
- Transparency & Control: Users can see, understand, and modify the source code. This is invaluable for research, advanced industrial applications, and building trust in the simulation results.
- Extensibility: The architecture allows engineers and scientists to add new models, solvers, and functionalities tailored to their specific problems – something often restricted in commercial packages.
- Community Driven: While CFD Direct spearheads development and offers professional support & training, OpenFOAM thrives on its global user community contributing to its evolution.
Why Open Source CFD is a Game-Changer
The discussion repeatedly highlighted the inherent advantages of adopting open-source CFD:
- No License Fees: This significantly lowers the barrier to entry for individuals, startups, and academic institutions, democratizing access to powerful simulation tools.
- Unparalleled Flexibility: The ability to customize and extend the code means you’re not limited by a vendor’s development roadmap. You can innovate at your own pace.
- Deep Understanding: Working with open-source tools encourages (and often requires) a deeper understanding of the underlying physics and numerical methods, leading to better, more insightful engineering.
- Collaboration & Knowledge Sharing: The open nature fosters a rich ecosystem of shared knowledge, tutorials, and community support forums.
- Avoiding Vendor Lock-in: Users retain control over their tools and workflows.
OpenFOAM in Practice: Capabilities & Bridging the Knowledge Gap
OpenFOAM is a powerhouse, boasting a vast array of solvers and utilities for a wide range of CFD applications, including:
- Incompressible and compressible flows
- Multiphase flows
- Heat transfer and combustion
- Fluid-Structure Interaction (FSI)
- Advanced turbulence models
- Powerful meshing tools like

However, the speakers acknowledged that the learning curve for OpenFOAM can be steeper than GUI-driven commercial codes. This is where CFD Direct’s role becomes crucial. Dr. Jenya Collings elaborated on their mission:
- Expert Training: CFD Direct offers comprehensive training programs (Essential, Advanced, Programming) designed to empower users not just to use OpenFOAM, but to understand it. This transforms users from button-pushers into knowledgeable CFD practitioners.
- Professional Support: For organizations relying on OpenFOAM for critical projects, CFD Direct provides professional support, development, and consultancy.
- Sustaining OpenFOAM: Their work ensures the continued development, maintenance, and quality of the official OpenFOAM release.
The cloudHPC Supercharger: Making Advanced Simulation Accessible
Jousef Murad from cloudHPC emphasized how cloud-based High-Performance Computing is revolutionizing how engineers leverage sophisticated tools like OpenFOAM.
- Democratizing HPC: cloudHPC provides on-demand access to powerful computing resources, eliminating the need for expensive on-premises hardware. This means engineers can tackle larger, more complex simulations without hardware limitations.
- Ease of Use: Platforms like cloudHPC often come with OpenFOAM (and other engineering software) pre-installed and optimized, streamlining the setup process and allowing users to get to simulation faster.
- Scalability & Cost-Effectiveness: Pay only for the compute resources you use, scaling up or down as needed. This is ideal for fluctuating project demands.
- Collaboration: Cloud platforms can facilitate easier collaboration among distributed teams.
The synergy is clear: OpenFOAM provides the powerful, flexible software, and cloudHPC provides the accessible computational muscle to run it effectively.
Key Takeaways & The Future
The live session painted a vibrant picture of a future where open-source tools, backed by expert support and accessible HPC, empower engineers to solve increasingly complex challenges.
- Open source is not “free software” in the sense of lacking support: Organizations like CFD Direct provide the professional backbone.
- The learning curve is an investment: The deeper understanding gained pays dividends in better engineering.
- Accessibility is key: cloudHPC and similar platforms are breaking down barriers to advanced simulation.
This insightful discussion underscored that the power of open-source CFD, particularly with a robust tool like OpenFOAM and the backing of CFD Direct and cloudHPC, lies in its ability to empower engineers with unparalleled control, flexibility, and accessibility.
