What is stored in the appdf format files generated by Aspen PLUS?
Thread Content
During the use of B-JAC, when an appdf file was specified in B-JAC, it was found that the program required VLE data to be entered. Upon checking the original Aspen Plus file, it was seen that a refining template was being used, which did not contain any VLE property data. The VLE property data was entered manually, saved after that, and then B-JAC was reopened – only to find that VLE data still had to be entered. This phenomenon does not occur when using chemical templates for the simulation process. I guess it has something to do with the content stored in the appdf file; obviously, the appdf file is used for transferring data. What is an appdf file used for? What’s the use of it/why is an appdf file generated every time the Golf course apw file is run? This post was last edited by Breeze of the Sea and Rivers on 2007-11-21 at 12:55
Problem Definition *.appdf Binary Binary file containing arrays and intermediate convergence information used in the simulation calculations
Is it updated every time it runs? :(
I would like to ask how you imported appdf. After I tried to import it, VLE data was generated, but it was indicated that the file could not be saved. It also said that the Aspen file cannot be modified. Could you please give me some guidance? Thank you
How is data imported upstairs?
Problem definition: *.appdf binary – the binary file contains arrays used in numerical simulations as well as information regarding convergence
This file is an Aspen Plus problem definition file; it stores component information and is a binary file, meaning it cannot be opened in text format. When importing it using EDR, the versions must match. If AppDF is to be used, it must be exported in the same version. Of course, such files are also generated during execution – not only APW but also BKP.
