Problem of higher variability parameter.
Problem of higher variability parameter.
Hello
I have a problem to use thermocyle module added at openmodelica with externalmedia.
The problem is located on the calculation of sound velocity with the function of setState_pT.
In searching on google, I think that the problem from to evaluate pure /impure function.
Is it possible to add test loop on pure function ?
Modelica.SIunits.Velocity C_thr(start=Medium.velocityOfSound(Medium.setState_pT(p_choked_start, T_su_start)));
When I change this function in constant, the problem appears on this following function :
CheckCoolPropOptions
Can you advise me to modify this line ?
Thank you for your help
Steven
Thank you
Re: Problem of higher variability parameter.
In testing other module, I have always a problem with setState__pT.
I think this function don't return the right parameter.
function setState_pT
"Return thermodynamic state record from p and T"
extends Modelica.Icons.Function;
input AbsolutePressure p "pressure";
input Temperature T "temperature";
input FixedPhase phase = 0
"2 for two-phase, 1 for one-phase, 0 if not known";
output ThermodynamicState state;
external "C" TwoPhaseMedium_setState_pT_C_impl(p, T, state, mediumName, libraryName, substanceName)
annotation(Include="#include \"externalmedialib.h\"", Library="ExternalMediaLib", IncludeDirectory="modelica://ExternalMedia/Resources/Include", LibraryDirectory="modelica://ExternalMedia/Resources/Library");
end setState_pT;
I think my problem is principally on this function
