Modelica.Fluid and Media

Jan-25-12 20:18:55

I try  the newest nightly and try to use parts of the Fluid Lib but it not work fine so i try to test the examples

I picked the model Modelica.Fluid.Examples.Tanks.TanksWithOverflow
but the model checker give me following message:

Code:


[C:/OpenModelica1.8.0/lib/omlibrary/Modelica 3.1/Fluid/Pipes.mo:21:5-40:85:writable] Error: No matching function found for Medium.density(flowModel.states[1])

of type

  .Modelica.Fluid.Pipes.StaticPipe.Medium.density<function>(state:record Modelica.Fluid.Pipes.StaticPipe.FlowModel.Medium.ThermodynamicState

end Modelica.Fluid.Pipes.StaticPipe.FlowModel.Medium.ThermodynamicState;) => Real(min=0.0, max=100000.0, nominal=1.0, start=1.0, quantity=\"Density\", unit=\"kg/m3\", displayUnit=\"g/cm3\") in component pipe

candidates are 

  .Modelica.Fluid.Pipes.StaticPipe.Medium.density<function>(state:record Modelica.Fluid.Pipes.StaticPipe.Medium.ThermodynamicState

Integer(min=0, max=2) phase;

Real(min=-100000000.0, max=100000000.0, nominal=1000000.0, quantity=\"SpecificEnergy\", unit=\"J/kg\") h;

Real(min=0.0, max=100000.0, nominal=1.0, start=1.0, quantity=\"Density\", unit=\"kg/m3\", displayUnit=\"g/cm3\") d;

Real(min=1.0, max=10000.0, nominal=300.0, start=300.0, quantity=\"ThermodynamicTemperature\", unit=\"K\", displayUnit=\"degC\") T;

Real(min=0.0, max=100000000.0, nominal=100000.0, start=100000.0, quantity=\"Pressure\", unit=\"Pa\", displayUnit=\"bar\") p;

end Modelica.Fluid.Pipes.StaticPipe.Medium.ThermodynamicState;) => Real(min=0.0, max=100000.0, nominal=1.0, start=1.0, quantity=\"Density\", unit=\"kg/m3\", displayUnit=\"g/cm3\")

Error: Error occurred while flattening model Modelica.Fluid.Examples.Tanks.TanksWithOverflow

I have similar Problems when i want to use Modelica.Fluid.Pipes.StaticPipe i try different Mediums packages of water already.
Anyone have a Idea what wents wrong, or i did wrong????

Hi,

We don't fully support Modelica.Fluid yet.
We can flatten Modelica.Media but we cannot simulate all models.
We are working on fully supporting these libraries but it will take some time.

Cheers,
