I am trying to parameterize the reaction rates in ANSYS Fluent. And for that, I am supplying the following TUI command.
(rp-var-define 'param 2 'integer #f)
Be noted that I am a complete newbie and it is the first TUI command I am writing.
I am getting the following error.
> (rp-var-define ‘param 2 ‘integer #f)
Error: eval: unbound variable
Error Object: �eparam
Can anyone help me resolve it?

That's an rp-var command, not a TUI command. Where did you find it?

I am sorry but where should I write that command ? In the Fluent console right?

In the TUI panel, but as it's an rp-var (sets something in the backend of the solver) I would use with some caution.

In that case, what is the best way to parameterize activation energies and pre exponential factors of reactions in chemistry solver ?

Thanks. However, the problem is not the complexity of the reaction. The problem is that I want to run my simulation about 100 to 200 times for different combinations of reactions' activation energies and pre-exponential factors. Doing that manually would be a hassle. I was thinking if somehow I could make them the parameters and using DesignXplorer DOE automate the process. In that case, I thought that may be, the rp-var command might help, but got the error (as in my first comment).

The rp-var command may work, but check the syntax. Scheme is sensitive to misplaced spaces and '
