Hello friends,

and i make a debug for it and locate the were the error but i found that equation correct not divide to zero and all variables correct what can i do .........

thanks

I would suggest to just keep on checking/debugging as it could be anything... FORTRAN is notorious for giving error messages without much explanation. But for sure somewhere there must be a little error, or typo, or wrong input format,... it also depends if it is a linux or unix compiler (I don't think the microsoft FORTRAN is still around or has any support).

good luck.

I would remove all of the optimizations and try to compile with the option "-check all" (work for the Intel compiler, but sure there's something similar in all). I found most of the times it gives better clues as to where the error is

You guys really need to be more specific on this stuff, Ie include a code fragment, what compiler/ compliler flags. I know GCC/GFortran has a -ffast-math flag that assumes all the numbers are valid which speeds up the runtime but doesn't include checks for infs or nans which can cause weird issues.
