62 PROCESS SIMULATION AND CONTROL USING ASPEN

Running the simulation

In Figure 2.12 , Status message includes Required Input Complete. It implies that
all
required input information have been inserted by the user. There are a few wa ys to
run the simulation. We could select either the Next button in the toolbar which will t ell
us that all of the required inputs are complete and ask if we would like to run th e
simulation. We can also run the simulation by selecting the Run button in the toolba r
(this is the button with a block arrow pointing to the right). Alternatively, we can go to
Run on the menu bar and select 'Run' (F5).

Viewing results
As we click OK on the above message , the Control Panel appears showing the progress
we notice that the Results
of the simulation. After the simulation is run and converged ,
Summary tab on the Data Browser window has a blue checkmark Clicking on that tab
.
it should state
will open up the Run Status. If the simulation has converged ,
"
Calculations were completed normally" (see Figure 2.13).
Pressing Next button and then OK, we get the Run Status screen . In the subsequent
f
step, select Results Summary/Streams in the list on the let and obtain the final results
(see Figure 2.14). Save the work done by choosing File/Save As/...in the menu list on
the top.
Ifwe click on Stream Table knob just above the results table, the results are recorded
in the Process Flowsheet Window, as shown in Figure 2.15
