CAPE-OPEN

I corrected the special property argument in my code.
So far, I thought temperature, flow and pressure are quite common properties. That's why I set that special parameter to 'false'
The other reason: I use COCO/COFE for testing and expected it to use "Material11". There the 'special property' parameter is not used.

The problem persists and I send you the code.

There were several issues with the code. I returned some corrections via e-mail. Let me know if the problem persists.

greTol you'd better understand the "MixerSplitter" Unit Operation firstly, it's good for your creation of new modules.
