Help needed with answers to CFD interview questions
I will be appearing for a CFD Analysis job interview, I need some help with an interview question which I came across during my interview preparation:
How do you know your solution is the correct one if there are no experimental solution available for comparison?
I know it sounds a bit "basic". However, I got to thinking because there could be a number of ways to deal with it. One solution could be to check by reducing the grid size, and with a smaller time-step and see that the error asymptotically reaches 0. But this is a convergence validation, right? We still do not know for sure that the solution is correct.
Please let me know if my understanding is correct on the above, and also what would you answer for this question if asked in an interview?
