simulation using fortran

hello

i wonder if any of you can help me with this, i'm trying to write a
simulation program by using fortran language (my complier is MS
fortran PS) , and if anyone can tell me is there any textbook or
article or something that i can use for reference, especially the one
with example would be great. or if you have any expirience in doing
so, your comment will be highly appreciated.

thanks so much

That isn't enough of a description to be helpful. "Simulation" covers
far too wide a range of things to be very descriptive.

That's probably a mistake. That compiler hasn't been supported for about
a decade and was seriously buggy.

All I can suggest from your description would be general Fortran
textbooks. Recommendations on those have been posted here regularly. But
they aren't going to say much useful about "simulation" as a general
category.

I agree that one should know more about the type of simulation,
but I might recommend "Numerical Recipes" anyway. It is full of
examples with reasonable explanations of how they work.

The explanations are good, but there's a proprietary module that you'd need
to purchase if you're really going to do any damage with it. I don't think
this customer is in the market for that.

There's at least two types of sims. Those with a picture and those without.
Fortran excels with the latter. So it is that we can simulate the stress on
a truss. The only "picture" this gives is that if something fails, it comes
down on your head. Fortran only informs other applications as far as the
picture goes.

I'm writing a simulation program too. It involves various serial
digital I/O devices, lots of discrete, analog, and synchro inputs and
outputs, data acquisition/processing, graphing/plotting, and GUIs to tie
it all together, all in Fortran (well I have to call a C API for most of
the I/O drivers, but otherwise its in Fortran). I recommend you at
least use a more recent compiler such as Intel Visual Fortran. I'm
actually still using Compaq Visual Fortran, but I believe it will be a
relatively minor upgrade to IVF when the time comes.

Not the Fortran 77 and Fortran 90 versions; for Fortran 90 there is even
a utility module which has been put into the public domain, if memory
serves correctly.

As has been said many a time in this group, VB/Delphi ease putting
together a pretty front end; and there are Fortran-based GUIs that are
commercially available - see polhedron.co.uk for examples.

Finally, tour 'simulation framework' needs to define as a minimum if you
are looking at a PDE or ODE system, or perhaps steady-state/algebraic
equations, or something more akin to queing theory - there are plenty of
good books, but 'simulation' by itself is too large a topic to pin down.

Yes, those are some of the categories I was thinking of. Most of fhe
issues involved in doing, say, a real-time simulation of an ODE system,
perhaps with hardware interfaces, are a *LOT* different from doing a
queing theory simulation. And then there are things like electronic
circuit simulations (SPICE et. al.) and who knows what else. Fortran is
often used in those kinds of sims. I don't think Fortran is typically
used in things like MMORPGs such as World of Warcraft, which are
certainly simulations and have yet another very different class of
issues. In some sense, one could think of most computer applications as
being simulations of something.
