[TRNSYS-users] Type 618_Limited maximum pressure

Hi every one,
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:
1. 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.
2. 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?
Thanks in advanced
JAvi
