<p>Hatem,</p>
<p> There is not really an easy way to debug this problem. The
cooling tower is unable to solve at a particular point in the
simulation. Make sure that you are not trying to use the cooling
tower in a cold climate during winter. Freezing water in the
cooling tower can cause the model to have a hard time solving (and
in any case it can cause real life problems to run cooling towers
in cold winter climates). If that is not the case and if you have
made sure that your cooling tower parameters are realistic and
that the tower is appropriately sized to the load then I would
recommend sending your project to your distributor for assistance.</p>
<p>kind regards,</p>
<p> David</p>
