CAPE-OPEN

GetOverallProp is defined as following:
GetOverallProp(CBSTR(L"temperature"),NULL,&v).
When I use GetOverallProp to obtain the product stream temperature, the process that does not contain virtual components can be obtained normally, but the process that contains virtual components fails to obtain, I want to confirm whether the thermodynamic interface has any special treatment for the process containing virtual components .

Can you tell which software you are using?

I am using the software implemented by our team for process simulation. But I'm sorry to interrupt, I found that I was thinking wrong, it shouldn't be because of the interface, thank you for your reply.
