Counting subroutines in parallel

My problem is that I'm trying to speed up some modeling code and I need to count how many times my subroutines get executed and if I were writing this in sequential c++ I would have no problem, but I'm writing in the unfamiliar Fortran 77 and the code is running with OpenMP. I would also have no pro...

Re: Simulation of a bending plant stem

What about doing a fluid flow of a flat plate and assume it's laminar all the way across. You could then do a finite difference method (not all that challenging) on the system to get data points at some distance and draw a curve between them.
