VC++编程求解粘性不可压缩NS方程,请各位高手建议
Java certainly is not a choice for scientific computation since
it is so slow. C++ is more natural and good for development of
large software. If you write a code only for Euler flow, the
code is not that large. If you wish your code has more
functionalities (more turbulent models and handle all speed flows,
has integrated preprocessor and postprocessor), C++ is the best
choice. Speed is a big issue in CFD. With fast growth of processor
speed and parallel computing, memory problem is more concerned
because people want to solve bigger and bigger problems. In
addition, reusable and maintaince are very important for a
software because it decides the price of a software. Another
thing is C++ is compatible with C. What you can do in C, you
can do it in C++ too. Memory leak is the biggest pain in C++.
C and Fortran have the same problem if you use any pointers. |
