Passing Data from One Screen to Another Screen Back to Main Tutorial

If you go to Preferences\ Data Passing Options, you should see three options: 1) Ask before Data Pass, 2) Do NOT Ask and Pass Data, 3) Do NOT Ask and Do NOT Pass Data

The following steps will explain the functionality of the three options above. GCAP allows you to bring appropriate data from one screen to another screen. For example, you are doing flash calculation on screen 5A and you want to know the phase envelope of the gas, you can open screen 4A and GCAP CAN pass that gas composition to screen 4A for you, depending on the option that you select. You do not have to retype the gas compositions in the screen 4A. Assuming that here is what you have on screen 5A:

Now you are ready to do the flash calculation. Click the “Run” button. Please notice that the information you type in will not be remembered by GCAP until you click the “Run” button. You should see the following after clicking the “Run” button.

Option 1: (Ask before Data Pass)

Let’s go to Preferences\ Data Passing Options and select option 1. Go to the Volume 1 menu, click Chapter 4. Phase Diagram, and select A. Multicomponent Phase Envelop. GCAP recognizes that you have existing data that could be used in this screen 4A. Because you select option 1 (Ask before Pass Data), it asks you to update the data or not.

If you click Yes, the gas compositions you typed into screen 5A is now displayed in screen 4A

If you click No, all the gas compositions remain zero.

Option 2: (Do NOT Ask and Pass Data) If selected, GCAP passes the data to screen 4A without asking your permission.

Option 3: (Do NOT Ask and Do NOT Pass Data) If selected, GCAP NEVER asks and NEVER passes existing data to screen 4A.
