Hi Hamza,

To interact with a user model subroutine in Aspen Plus and link it with MATLAB and Excel, you can perform the following steps:

• Create the user model in MATLAB and prepare an Excel interface for the same.
• Set up a user block model in Aspen Plus and connect the necessary streams
• In the Aspen Plus block, specify the name of the excel workbook created, and enter the operating parameters.
• Use Excel’s VBA to call the MATLAB script and retrieve the output data.
• Run the simulation in Aspen plus. The data should flow from Aspen Plus to Excel, then to MATLAB, and back in the same order.

For more resources in connecting Aspen Plus, MATLAB and Excel, you can refer to the following links:

Hope this helps!
