Kent,<br>
I think that the DLL you are running and the Fortran code that you
attached are not quite the same. I had to make a few changes in the
source code before I was able to run the project that you sent. When I
did run the project, I got an error when the variable PRPIPEFILM got
set to a negative number, then got raised to a non integer power during
the Type's iteration. The offending equation is:<br>
<br>
NUPIPEFILM=(0.6+0.387*RAPIPEFILM**(1./6.)/(1+(0.559/PRPIPEFILM)**(9./16.))**(8./27.))**2.<br>
<br>
I hope that helps...<br>
