Computational fluid dynamics (CFD) is a powerful tool for aerospace engineering, but it also requires collaboration and communication among different experts and engineers. How do you work with other CFD professionals and ensure that your results are accurate, reliable, and useful? In this article, we will explore some of the best practices and tips for effective CFD teamwork.
Before you start any CFD project, you need to have a clear understanding of the problem you are trying to solve and the scope of your analysis. What are the objectives, assumptions, constraints, and criteria of your CFD study? What are the inputs and outputs of your model? How will you validate and verify your results? These questions should be discussed and agreed upon with your colleagues and clients, and documented in a project plan or a statement of work.
There are many different CFD software packages and methods available, each with its own strengths and limitations. Depending on the complexity, scale, and physics of your problem, you may need to use different tools or techniques to achieve your goals. For example, you may need to use a structured or unstructured mesh, a steady-state or transient solver, a laminar or turbulent model, or a coupled or uncoupled approach. You should consult with other CFD experts and engineers to select the most appropriate software and methods for your problem, and justify your choices with references and evidence.
As you work on your CFD project, you should communicate and document your work regularly and effectively. You should share your progress, challenges, and feedback with your team members and clients, using appropriate channels and formats. For example, you may use email, phone, video conference, or online platforms to communicate, and reports, presentations, or code blocks to document. You should also follow the standards and conventions of your organization and industry, such as naming, formatting, and referencing. This will help you avoid confusion, errors, and conflicts, and ensure that your work is transparent, reproducible, and traceable.
Once you have completed your CFD simulation, you should review and validate your results carefully. You should check your results for consistency, accuracy, and plausibility, using various methods such as grid convergence, sensitivity analysis, uncertainty quantification, or comparison with experimental data. You should also solicit feedback and suggestions from other CFD experts and engineers, who may have different perspectives, insights, or experiences. You should be open to constructive criticism, and willing to revise or improve your work if needed.
The final step of your CFD project is to present and apply your results to your intended audience and purpose. You should present your results in a clear, concise, and compelling way, using appropriate visuals, tables, charts, or graphs. You should highlight the main findings, implications, and recommendations of your CFD study, and relate them to the original problem and scope. You should also apply your results to support your design, optimization, or decision-making process, and demonstrate how your CFD work adds value to your aerospace engineering project.
CFD is a dynamic and evolving field, and you should always strive to keep learning and improving your skills and knowledge. You should stay updated on the latest developments, trends, and innovations in CFD, and seek opportunities to learn from other CFD experts and engineers. You can join professional associations, attend conferences, webinars, or workshops, read journals, books, or blogs, or take online courses or certifications. You should also reflect on your own CFD work, and identify your strengths and weaknesses, and areas for improvement.
Learning the history amd most important publications in a given field is incredibly important and CFD is no exception. To gain a strong foundational base, read some of the earliest and most important CFD papers, which mainly came out of Los Alamos National Lab.
While it's important to learn the equations and physics behind the simulation, it's equally important to understand the ins and outs of whatever software you're using. Rarely in industry are the equations directly interacted with, and knowing the pre-processing, solving, and post-processing capabilities of your particular software are how you get results as an engineer.
