[TRNSYS-users] Slow model at boiler pressure of 10000kPa

[Amir Nashed]

Dear TRNSYS users

For some reason all steam components at P=100 Bar (10,000 kPa) go very slow, whether it is a preheater, condensate pump..etc
The issue is not with the model, as I isolated the components, for example simulated type609 by itself and still did not work. . I believe the reason is the the Steam_Properties() subroutine as when I tried to use Type58 just by itself at the same steam properties, the same issues occurred. When I reduce the pressure to 9300 kPa, it works fine.

Inputs:

Does anyone know how to solve that?

I can change the pressure, but I believe 100 bars for boiler pressure is pretty standard
