STAR-CD v3.26: Select Analysis Features -> Reacting Flow : 1) Chemical Reaction, 2) STAR/KINetics. What's the principal difference between 1) and 2) ? I haven't found any example in tutorial connected with using STAR/KINetics feature. Can anybody help me?

STAR/KINetics is an add-in which costs more money and does much more complex reactions based on CHEMKIN. Your installation should have the manual for STAR/KINetics under Help, Methodology.

Another product called DARS is also now available to do similar work.

Before parting with money get some clear proof that any kinetics add on tool from adapco can run more than a single tutorial example.

Maybe the position has changed in the last year.

Reaction Design and adapco do not work together anymore. The split came first, investment into DARS second ...
