Dear all, I was wondering if someone could help out please. I am trying to make HYSYS pick random sets of inputs that could run upto a million, process each sample set based on my model built in HYSYS and thus give random outputs. The random inputs are generated using Matlab.In this way; i will end up with a table of random inputs and the corresponding outputs. Can someone help out please.

(For fewer sample sets, I found that one can use HYSYS datebook/worksheet to manually substitute the input sets and get outputs; however, this method becomes somehow impractical when one is dealing with sample sets running into millions).

in my opinion running millions of cases of process calc's (even a simple VLE flash on a multicomponent mixture may take several seconds) is not a realistic objective on std. 3GHZ computers,
you can do that with a supercomputer or waiting months for the solution.
I utilize Matlab with Prode Properties,
with Prode Properties you get macros to access almost all the methods in the library.
When executing from Matlab consider an additional time delay due to Matlab interpreter, you can compile but it's about the same.
I prefer Matlab when optimizing specific process parameters, Matlab allows to minimize complex functions and find the optimal design.
