Hi Paule, I use Delphi for simulating motor vehicle assembly line operations. This is not computationally intensive and performance is no problem. Compared to Fortran the developpment time is much quicker.
I also have a small but computationally very intensive optimization that was originally in Fortran. One issue here is Delphi's memory management. It is slow to dynamically allocate and free memory, so I calculate what I'll need up front. I have heard about 3rd party improved memory managers but haven't tried them. They would be more important to me if I could not allocate my memory up front.

I would like to be able to implement numerical integration routines and test them on a standard problem set for various sets of parameters and input data. I would then like to represent the results, typically image transformations, graphically. I can paint and test GUI's rapidly in Delphi, although connecting them to numerical code is sometimes tricky. Is there some way of making three "plug boards": a GUI layer and a test problem layer and a numerical routines layer such that they can be interconnected much like a telephone exchange routining calls where they need to go given the number that was dialed? In a way this question harkens back to Robert's response to the business logic vs gui layer question. Can anyone elaborate that in this case? Any thoughts on this matter would be very useful.
