High Pressure Water Properties into SAM

I'm running the Process Heat Parabolic Trough simulation. I get a warning when entering water outlet temperatures above 300C which they can be if a very high pressure system is being simulated. Pressure can be up to 11MPa. Is the warning real? Is there a database I can input for higher pressures and temperatures. Any help is appreciated. Thanks (newbie to SAM)

Dear Allan,

In case you haven't seen it, the following video introducing the IPH trough model might be helpful:

In general, when you change design parameters like the loop HTF temperatures, you may need to adjust other parameters accordingly. You can explore the outputs to see if the operating temperatures and pressures are what you expect, and then make adjustments to inputs.

If you need more help, please tell me what specific error you are seeing, and if possible attach your .sam file (edit your original post above) so I can better understand what you are describing.

Best regards,
Paul.
