behaviour<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>Hi everybody,<br>
I'm having some problems with a type I'm developing... I'm using Compaq Visual
Fortran 6.6.c.<br>
<br>
Here's the problem, I have these simple line of code, some variable's names are
in italian but there's no problem I hope...<br>
<br>
T_sonde=(T_rit+Q_h*(1-1/COP)/(m_acqua*Cp_sonde))*(fattore_carico)+T_rit*(1-fattore_carico)<br>
<br>
The problem is that if I pass the right value to m_acqua (which is a flowrate)
I get an "Invalid floating point operation" error. The correct value
for m_acqua si 1500 kg/h which I converted in kg/s, 0.416667. If I pass this
value I get the error, if i raise to 5-10 kg/s there's no error. If I raise
only to 2-3 kg/s the simulation lasts longer but eventually gives an error...<br>
<br>
Where can the problem be?<br clear=all>
<br>
Many thanks,<br>
Matteo.<br>
