Re: Variable and class not found in Modelica.Media

[Martin Sjölund]

Hi,

Modelica.Media is one of our priorities right now. I didn't check your 
log or mo/mos files because I recognize the error messages. The errors 
you are getting is because specificEmpalthy_ptx (or whatever it's 
called), is a partial function that should be redeclared by "redeclare 
replaceable function extends specificEmpatlthy_ptx algorithm ... end 
specificEmpatlthy_ptx;".
We currently only perform the extends part of it, and put the new class 
in our class. However, we don't redeclare it in the base class.

Hello, everyone! 
 
I'm interested in using Modelica.Media delivered with OpenModelica 1.5.0 
RC1. My first simple test model ("media_test.mo") initializes 
"AbsolutePressure" and "SpecificEnthalpy" 
from "Modelica.Media.Water.WaterIF97_ph", and contains no complicated 
calculation. I use the "media_test.mos" to load the Modelica library, 
load the model file, and then simulate it.
 
But the simulation fails, yielding errors about missing variables and 
classes ("media_test.log"). Typical errors are:
 
Error: Class Modelica.Media.Water.WaterIF97_ph not found in scope 
media_test.Medium.
 

Error: Variable nS not found in scope 
Modelica.Media.Interfaces.PartialTwoPhaseMedium

 

Error: Class 
Modelica.Media.Interfaces.PartialTwoPhaseMedium.FluidConstants not found 
in scope Modelica.Media.Water while instantiating waterConstants.

 

Can anyone help me with this? I really appreciate your help.
