Re: cofestand does not return handle to command line

I am not clear on your problem statement.

Can you first of all, when this happens, check with the task manager, or tasklist, whether COFE.exe and COFEStand.exe are still running at this point?

Secondly, which handle are you referring to? Presumably the STDOUT handle?

Re: Details on PropertyTester

The mole number derivatives represent the increase in enthalpy if you would add a component to the mixture, thereby increasing its overall amount. If you compare to molar enthalpy, you should take into account also the increase you would get from increasing the number of moles in the mixture. This m...

Re: Details on PropertyTester

Temperature and pressure derivatives are perturbed by a relative distance that can be adjusted from the unit operation's configuration; the perturbation is in the direction of positive T and P. Mole fraction derivatives are unconstrained and perturbed with a perturbation relative to 1, so the relati...

Re: Errors when I upgraded to Version 3.9

This is strange. Can you perhaps remove the entire registry key: HKEY_CLASSES_ROOT\CLSID\{429DC999-9073-4549-8647-BA72D6BE7931} and then try regsvr32 on COCOCOUS again? Perhaps there is something inside that key that does not belong there. Also, you are not starting COFE itself with administration r...

Re: Errors when I upgraded to Version 3.9

If the anwer to that is no, it looks like the compressor did not get registered properly. In this case, please re-install, or open a command prompt to go to the COCO installation folder, and in the x64 folder, try regsvr32 COCOCOUS.dll For an all users installation, the command prompt must be starte...

Re: Errors when I upgraded to Version 3.9

Can you insert a compressor into a new document?

Re: COCO 3.9 released

eNRTL requires reactive equilibria (at least in terms of true composition, the composition is a result of the equilibrium routine), so it is not really possible to do this until the upcoming reaction interface standard is published, and supported by COCO. And then still it requires a significant imp...

Re: COFE Flowsheet protection

Once you created the COM object you should be able to use all the same functions. There is no external stop function. This would also not be possible as Solve does not return control until it is done - it would have to be done from another thread, and the COFE object is apartment threaded (can only ...
