thanks Ejaz Haider..i have already gone through this paper but need some more expalnations as all things are not clear.
The following link can be very helpful: https://www.youtube.com/watch?v=imthvC5bW08
I recommend setting the variables that you want to manipulate or extract in the Hysys spreadsheet. In addition, it is advisable to place a pause in the execution of the MATLAB algorithm (using "pause (n)", n = seconds) to give hysys time to converge the simulation.
Dear Asma,
If you want an code example to linking Aspen Plus with MATLAB, please write me to the following email: [email protected]
As far as I know, you can't link MatLab with Aspen Plus. You can use, instead, ACM of Aspen to model your own unit and then link it with Aspen Plus. For example, you can build a model for a membrane using ACM and then add it as a new unit to Aspen Plus
Duran,
You said that put a pause to let HYSYS run to converge. I do not know whether this is necessary. I have tested the HYSYS-MATLAB program without using a pause, it worked well. But I did find some matlab code that use pause to give time for aspen plus to run as shown below.
Run2 ( AspenEngine )
while ( get ( AspenEngine , ’IsRunning’) )==1
pause ( 1 )
end

Exactly. The best option is with the while loop, taking the variable "IsRunning" as the stop criterion. This can be applied for Hysys and Aspen Plus.
I decided to put the requested example in matlab central. See the following link:

You actually can link Aspen plus to Matlab through Excel. When you choose USER 2 model unit you will find out there is a path that Aspen plus links to the Excel file in the same folder where the ASPEN plus file is, containing inputs and output streams. Then, you can link Matlab and excel as it is explained elsewhere in the Matlab tutorials (by using read, write commands). Perhaps you can find these files interesting and contact the researchers for further info (see annexed file)
Aspen plus and MATLAB can directly connect to each other and make a good interface.
