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: 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 ...

Re: COFE Flowsheet protection

... down side is that apparently Excel can only contain 32000 or so characters in a cell: https://techcommunity.microsoft.com/t5/ ... /m-p/66355 - for larger strings you need to find a different way, e.g. split it up over multiple cells.

Re: COFE Flowsheet protection

I am not sure whether this can be done. As the flowsheet is embedded as OLE object, Excel decides whether it should be saved or not. I suppose that if you edit the flowsheet after the solution was imposed, Excel will assume the OLE object was changed and it will be saved. But I do not see an easy wa...

Re: Normal volume flow computation

The MeasureUnit help explains what the MeasureUnit does: https://www.cocosimulator.org/index_help.php?page=COUS/measureunit.htm I do not think there is one single definition that fits all purposes. If you need the ideal gas volume, I suggest you use the approach you sketched with the information cal...
