User Defined Reaction Rate

John McKelliget

I dont understand how a UDF for a reaction rate, which is attached to the appropriate function hook, is then attached to a reaction in the reaction panel. All I get are inputs for arrenhius reactions. Also, what if you have more than one reaction - there is only one function hook.

I know I am missing something basic but the manual does not address this issue.

I am using finite rate model, three species, two reactions.
