CFD in C or C++

Hi there,
As I just have started programming CFD in C++ I am asking for some references or sites on the net about numerical recipes or CFD codes in C++. My thinking is that it is much easier to look at codes which are already written in C++ than translating existing Fortran codes. Many thanks in advance for your help and cooperation. Thorsten |

Are you planning to code the solver in C++? If so, is this to examine C++ capabilities, to examine CFD algorithms or to develop a code to examine physical problems? I suspect it is not the latter if you already have exisitng Fortran codes?
Peoples experiences of developing solvers in C++ and the reasons why some are moving from Fortran to C++.(and why some have moved back to Fortan again) may make an interesting discussion topic. I would exclude pre and post processors because the reasons for coding those in C++ are compelling. In answer to your question - there is quite a lot of C++ solver code out there. For example - diffpack is fairly well developed example at http://www.nobjects.com/Products/Diffpack - overture (built on A++/P++) is another good example http://www.c3.lanl.gov/%7Ehenshaw/Ov.../Overture.html - the object orientatated numerics page has a lot of links on the subject: http://monet.uwaterloo.ca/blitz/oon.html |

My son's idea was to look for a translator program between Fortran and C++ or C. Somebody must have done just that when C and later C++ were created. If you like to use a specific library of classes, then you need to get familiar with that particular library first.
