Hi every one,<br>
<br>
I am trying to simulate solar power plants, but I got the following
errors within the pump, type 618, in a simple case as the enclosed
one:<br>
<ol>
<li>If inlet pressure is 0.05 bar and outlet below 90 bar, it
works well. But if outlet pressure is set above 110 bar you get:
"run-time error M6201: Math - : Domain error..." You get the
same error even if inlet pressure is higher. Did anyone find the
problem, or a solution? Is this parameter limited to any value?
I have checked the source code, but I could not find the error.<br>
</li>
<li>On the other hand, the 2nd parameter "Thermal Loss Fraction"
looks like should be higher than the "pump efficiency". It
means, big numbers such as 0.8, 0.9.... And not 0.15. In the
examples (Rankine cycle, Steam-electric power plant) this
parameter is called "Pump motor efficiency". Which is the right
name? <br>
</li>
</ol>
Thanks in advanced
