Hi all, I would be grateful and appreciative to any person who contributes to this discussion topic. It is evident that CFD works (at the moment) are done especially at the reputable companies and research centers as a teamwork. I would like to get an idea about how are they "CFD tasks" delegated to people (grid generation, mathematical modeling, solution algorithm, …., etc). and who are responsible from doing each task, for example who are responsible from grid generation, are they mathematicians, engineers or computer science specialists, and so on the combustion modeling, the boundary conditions specification, …. etc.) when there exists a CFD problem how does it discussed at the beginning, is it through meetings between the group committee or it is discussed by a single expert person and then delegate the tasks to the several specialists. For those working in these reputable companies and research institutes are they glad about the current way of delegation of responsibilities? nice to hear about personal experience in this field, comments and suggestions. waiting for a fruitful discussion.

you do not need a team to do cfd. you can just have one guy to do grid, solver, simulation, and post processor.

may be you are right for small CFD Jobs but for the large ones I don't think so. for example airoplane engine development, could it be done by one person?.

That is exactly what I do, one man in airplane company,or engine company. It all depend who you hire, and how much you want to spend. NASA have a lot of people in cfd, specialize in every field, research and development.

Hi,

I don't think it really works the way you describe it here (at least not in our place). In my job it's more the case that you are given a certain project to do (ideally after thorough discussion with other departments, e.g. design or development) and you usually do the whole from start (i.e. grid generation) to finish (post processing). I can't imagine that it is really different in other places. You probably find it that sometimes the grid generation is done by a consultant engineer if you have to much to do or you outsource your actual calculation if your hardware isn't powerful enough for the job in hand, but I think it wouldn't be very practical to generally seperate the different tasks of CFD. Especially when you think that some jobs are quite time consuming and can be quite tedious (meshing) and other jobs are done relatively quickly. I don't think many people with CFD skills would want a job where they do nothing but meshing or nothing but post-processing. What is more interesting regarding team work is probably the question what part CFD plays in your development- ,sales- or whatever-process.

Hi, thanks for contributing, but I think what I describe "CFD as a Teamwork" depends on the complexity of the job to be performed, for example I cann't image that only one person could model or run a CFD Model with Fluid flow with turbulence+moving Boundary+Combstion+Phase Change+heat transfer+.....+etc for a complex geometry. unless he is a superman. You said that "(at least not in our place)." kindly descripe the activities you do in your place to see whether it include the real complexities found in CFD. Thanks

Hi, thanks for contributing, in this firm are responsible from the hole CFD stuffs? do design or analyse the wings+the engine internal flow+combustion effeciency in addition to the aerodynamic body of the aeroplane+.....?

The point is that the task will be simplified, assumptions made etc. so that it becomes the task of a single person. From a business point of view this is far more attractive than the academic approach that would ensure that, to satisfy an 'absolute accuracy at any cost', many different groups from different disciplines were combined to tackle a multi-physics or multi-component type problem.

I'm assuming here that you haven't worked in a profit orientated commercial environment where CFD is (correctly) viewed as a tool. As such it has to be profitable and useful. Accuracy comes later ...
