SUMMARY

The discussion centers on writing a simple Computational Fluid Dynamics (CFD) code to solve flow problems, emphasizing the importance of grid generation, solver implementation, and post-processing of results. Participants suggest starting with a quasi-1D CFD code, which can be developed in approximately one month for those with adequate knowledge. The conversation highlights the complexity of CFD algorithms, likening the task to a Ph.D. dissertation, and encourages seeking resources that provide sample codes for guidance.

PREREQUISITES
  • Understanding of Computational Fluid Dynamics (CFD) principles
  • Familiarity with grid generation techniques
  • Knowledge of numerical methods for solvers
  • Experience in post-processing CFD results
NEXT STEPS
  • Research quasi-1D CFD code development techniques
  • Explore grid generation tools and methodologies
  • Learn about numerical solvers used in CFD
  • Investigate post-processing techniques for CFD results visualization
USEFUL FOR

Students, researchers, and engineers interested in developing CFD codes, particularly those focusing on flow problem solutions and numerical methods in fluid dynamics.

Dear all, Anyone can tell me about the algorithm to write a simple CFD code to solve a flow problem.starting from grid gen, solver,post results. pls refer some site providing sample codes.

Your question on grid generation, while vague, is approachable. What you're asking here is roughly the equivalent of a Ph.D. dissertation.

Perhaps you could start with a quasi-1D code first? A code like that could take as little as a months or so to write given you know what you're doing.
