in Aspen Plus, after selecting a component (for example, WATER), when you click on "Run" (the error "Unexpected end of file. The results are not loaded", the properties of substances from the component database are not loaded. In the "Control panel" the following information:

<< Loading Simulation Engine 21:09:53 Thu Apr 6,

*   WARNING IN PHYSICAL PROPERTY SYSTEM     

MW MISSING FOR COMPONENT NH3 

*   WARNING IN PHYSICAL PROPERTY SYSTEM     

NRTL BINARY PARAMETERS FOR ALL COMPONENT PAIRS ARE ZERO,    

YOUR RESULTS MAY NOT BE ACCURATE. PLEASE REVIEW AND PROVIDE BINARY     

PARAMETERS AS APPROPRIATE.

 

What to do?

Make sure your components are entered as 'conventional' which uses the built-in database. You may have added them as 'user added' instead.

Am I doing it right?

You need to resolve the Methods tab (red/white circle) on the picture on the right.

 

I see no issue on the picture on left.

It seemed to me that after selecting the component Aspen should redirect me to the "Analysis of properties", and I get into the control panel with this error "Results not loaded"

I started to master the program not so long ago, maybe I don't understand something, I apologize maybe for stupid questions...

Your screenshot shows you are running version 8 of the program. The latest version is 12. If you cannot run the program, the fault may lie with the installation.

I tried to install 8,9,10,12 and 14 versions. It's the same mistake everywhere. I do everything according to the instructions

Hi,

You may need to talk to Aspen tech support.

Good luck
