normally, simulation results are presented in a graphical form. i coded a program in c++ to simulate flow in channels. all the calculated velocities and pressure are stored in arrays. the problem is how these stored data be presented in graphical forms using c++, for example, the 2d and 3d velocity profiles. or it is necessary to have some sort of link to other software that can handle this task.

any advice is appreciated. thanks.

I also use C++. But I usually do not use C++ itself to see the graphical result. If you want to draw the depth there are many good graphers such as SURFER, SIGMAPLOT, etc. If you want to draw velocity vector, I will recommend TECPLOT. It can read text file. You just need to make the file as shown below.

I suggest using the GMV software (this will be independant fo your code)
