I am using PRO/II 9.2 alpha and I am starting from a case file where the CPP Ideal Thermo PPM and its PP nC6nC8 are plugged in. Then I am inserting the CPP MixerSplitter example UO, connected its two inlets and one outlet.

Then I am running the case, saving and exiting. This gives the attached log file. I am looking at the sequence of calls logged at the beginning of the Calculate call:

COLTT <Anonymous> : Call to GetOverallProp

GetOverallProp Takes Input arguments:

Property Basis pressure UNDEFINED

GetOverallProp Returns:

Property Basis ValueReturned pressure UNDEFINED 100000

COLTT <Anonymous> : Return from GetOverallProp - Succeeded COLTT <Anonymous> : Call to GetOverallProp

GetOverallProp Takes Input arguments:

Property Basis totalFlow mole

GetOverallProp Returns:

Property Basis ValueReturned totalFlow mole 1.25998

COLTT <Anonymous> : Return from GetOverallProp - Succeeded COLTT <Anonymous> : Call to GetOverallProp

GetOverallProp Takes Input arguments:

Property Basis fraction mole

GetOverallProp Returns:

Property Basis ValueReturned fraction mole 0.3

0.7

COLTT <Anonymous> : Return from GetOverallProp - Succeeded COLTT <Anonymous> : Call to CreateMaterial COLTT <Anonymous> : Return from CreateMaterial - Succeeded COLTT Reference count for MO logger is 2 MaterialObject <Anonymous> : Call to CopyFromMaterial

It says that COLTT retrieves pressure, totalflow and composition. Well my reading of the CPP MixerSplitter source code tells me it is the Unit Operation which does that.

00195 first let us make sure we are in a valid state 00196 if (valStatus==CAPE_INVALID) 00197 {SetError(L\"Unit is not valid\",L\"ICapeUnit\",L\"Calculate\"); 00198 return ECapeUnknownHR; 00199 } 00200 if (valStatus==CAPE_NOT_VALIDATED) 00201 {SetError(L\"Unit has not been validated\",L\"ICapeUnit\",L\"Calculate\"); 00202 return ECapeUnknownHR; 00203 } 00204 ATLASSERT(valStatus==CAPE_VALID); 00205 init variables 00206 componentFlows.resize(nCompounds); 00207 for (j=0;j<nCompounds;j++) componentFlows[j]=0; 00208 totalFlow=0; 00209 enthalpy=0; 00210 pressure=0; 00211 loop over the connected feed ports, get the minimum pressure and the total component and enthalpy flows 00212 for (i=0;i<2;i++) 00213 {port=(MaterialPortObject *)portCollection->items[i]; 00214 if (port->IsConnected()) 00215 {get the pressure 00216 material=port->GetMaterial(); 00217 if (!material.GetOverallProperty(L\"pressure\",NULL,value,error)) 00218 {SetError(error.c_str(),L\"ICapeUnit\",L\"Calculate\"); 00219 return ECapeUnknownHR; 00220 } 00221 check count 00222 if (value.GetCount()!=1) 00223 {SetError(L\"Invalid values for pressure from material object: scalar expected\",L\"ICapeUnit\",L\"Calculate\"); 00224 return ECapeUnknownHR; 00225 } 00226 use minimum pressure 00227 d=value.GetDoubleAt(0);

00229 get total flow 00230 if (!material.GetOverallProperty(L\"totalFlow\",L\"mole\",value,error)) 00231 {SetError(error.c_str(),L\"ICapeUnit\",L\"Calculate\"); 00232 return ECapeUnknownHR; 00233 }

I am using PRO/II 9.2 alpha. I enable logging on the CPP Ideal Thermo PPM and on the TEA PPM. Then I open a new case file in PRO/II 9.2, go to Input
Thermodynamic Data, select CAPE-OPEN, then CPP Ideal Thermo PPM and its nC6nC8 PP, then I quit the view \"SimSci - Thermodynamic Data\" by accepting through OK once the System CO01 is shown. I get back in the same view through Input
Thermodynamic Data and there I select the PP C1_C2 (EOS) from TEA PPM; It makes the CO02 System within PRO/II. I quit this view and then I simply exit from PRO/II. This gives the log file attached. Look at it within the viewer. Near the end the Viewer displays \"Property Package <Anonymous> : Call to put_ComponentName while, when expanding it, it shows \"getPhaseList returns\". When looking at the log file with NotePad it is then obvious that a getPhaseList call has been logged not a put_ComponentName call.

I am starting from a case file out of PRO/II 9.2 in which three material streams have been drawn and two defined with flow, composition, pressure and temperature. The CPP Ideal Thermo PPM and its nC6nC8 PP are used. The scenario calls for inserting the CPP Mixer/Splitter Example in the flowsheet, access its CAPE-OPEN settings, change the heat input to 1, then connect the ports to material streams and run the simulation. It gives the log attached.

At the beginning of the Calculate method, the UO calls CopyFromMaterial onto a Material Object. The Material Object is mentioned as Anonymous. Within this call, it is logged that COLTT accesses the get_ComponentName method of the ICapeIdentification interface of an Anonymous MO: S1 is returned. Then the UO goes on by getting the present phases on a MO still mentioned as Anonymous. The CopyFromMaterial method has one argument, source. I think it would be wise somehow to mention the pointer value to the source MO. Further information could be displayed if indeed the get_ComponentName call succeeds like it is succeeding here.
