How to enter specifications from FraChem Column to RadFrac Column
When using OLI Engine in Aspen Plus, it is recommended that the end user enables OLI models from Aspen Libraries and use OLI's FraChem column. FraChem and RadFrac perform similar duties as 2-3 phase fractionation for a single column, model absorbers or strippers. When using FraChem it is imperative that you have OLI Chemistry model loaded in Aspen Plus.
See this for "How to use OLI Engine in Aspen Plus" : Installing_the_OLI_Engine_for_Aspen_PLUS
Below are the images for how the columns look like in the Aspen Simulation Environment. Please note that FraChem is an OLI ONLY Model Column and RadFrac is the Aspen equivalent of that unit operation.

RadFrac
FraChem Screens
OLI's FraChem column has the following specification options:
See this for examples on RadFrac and FraChem in Aspen-OLI : OLI_Engine_9.2_in_Aspen_Plus_User_Guide
How to open Input file
When you have a working example for a FraChem column ( Please refer to the OLI Engine in Aspen Plus User Guide for examples), open the Input file from home screen as shown below:
Copy Block Parameters
Scroll Down on the input file to find Block parameters and specifications:
Design Spec:
Copy the Content after the block parameters and keep it available on the clipboard.
Appending the input file for an OLI Chemistry RadFrac example
Open the input file for the already created chemistry model bkp file with a RadFrac Column. Scroll down to the bottom of the Input file where block parameters are:
Paste the data from the clipboard that you have copied before.
Save the input file as an inp file at the same location as the bkp file.
Open the .inp file
Right click and open the .inp file from the folder containing the bkp file with the Aspen Version that you need.
This should open similar content as your FraChem example file. Only difference is all your FraChem data is now in RadFrac Specification tabs.
Running from Command Line
Run the inp file from command line instead Aspen has the option Customize Aspen Plus :
