Hy everyone,
I'm trying to couple some output of a Matlab code with Fluent. Let me explain myself : i'd like to set as input parameter for the Fluent solver, a variable ( scalar) that come from matlab code. Is there any way to impose the location (path) of my variable ( saved from the matlab code) in the parameter set, so that i don't have to enter its value manually?

For example, i've a variable named a.txt , and i want to set it as an input parameter through the parameter set interface, how can i do?

Thanks for your help !

Hm, hopefully someone else here can cook up something more elegant, but this should do the trick.

Is there a reason you need to use Fluent parameters in particular? It will probably be easiest to do this with a scheme variable. Here's some unsanitary code that defines a variable "param" and reads the first value in "a.txt" into it.

Code:
(rp-var-define 'param 0.0 'real #f)
(define p (open-input-file "a.txt"))
(rpsetvar 'param (read p))
(close-input-port p)
Now that you've got a scheme variable with your value, you can use it pretty much anywhere.

Code:
(rpgetvar 'param)
