I'm pleased to announce the release of COCO 3.1. It is available from the [url]cocosimulator.org[/url] website, or you can update using COCO update (CUP)

Release 3.1 is a maintenance release. It collects all the fixes that have been made available over time via CUP into a new installer.

I hope you enjoy this new COCO release.

I would like to enter information in the streams as mass fractions rather that mole fractions. I am just unable to do this. I tried this by creating a custom units in preferences, and selecting "prefer mass that mole". But still the stream menu displays mole fractions.

Please select "Show mass fractions" from the Streams menu. Also available from the context menu (right click).

Thanks, appreciate your quick reply.

You are welcome. Note that this also changes the unit of measure for phase fractions. Plus it sets the default for new stream windows (and calculator windows, it works the same there).

After the latest update most of the unit operations are not available.

I cannot reproduce the issue.

Can you try running CUP again? If this does not fix it, please try registering COUSCOUS manually. From a cmd prompt, in the COCO installation folder:

regsvr32 COCOCOUS.dll
regsvr32 COCOCOUS64.dll

This may require administrative rights - depending on your installation (if you installed for all users).
