1. GUI For A Virtual Pipeline Simulation Testbed By, Revathi Manni Ranganathan Major Professor: Dr.Virgil Wallentine

2. Agenda  Pipeline Editor – Introduction  Previous Work by Oyenan  New Requirements  Design and implementation  User Feedback  Demo

3. Pipeline Editor- An introduction  Tool to create and manipulate virtual pipeline systems.  Window to the Simulators  Cut, Copy, Paste, drag and drop  Store / Retrieve pipeline system in.vps format  Visualize the results

4. Pipeline Editor  Developed using Java Swing, JGraph, Oracle 8i  Can be started on a remote machine  Requirements – Java Web Start, Web browser, JDBC driver  Connects to the Simulator on the remote server

5. JGraph  Graph drawing component purely in Java Swing  Based on Model-View-Controller framework  Graph Theory + Swing Architecture = JGraph  Provides cut, copy, paste, drag & drop, zoom

6. Pipeline Editor – A snapshot

7. Earlier Work by Oyenan  Basic Version of the GUI  Editor built on top of JGraph  Modeling of pipeline components – pipes, compressors  Job Control Optimizer  Result Visualization

8. New Requirements  Connector – generic type  Modification of Pipe  Compression Units  Connection to the Parallel Simulator  Connection to the Sequential Simulator

9. Connector  Generic Type Component  Multiple incoming and outgoing branches  Number decided by the user at run time  Replaces 2-way & 3-way Split, 2-way & 3way Combine

10. Pipes  Should support visualization of the leftmost and rightmost nodes  Implemented by class MyEdge – extension of JGraph’s Edge  Required modification in DataCell

11. Pipe – Snap Shot

12. Compression Units  Generic Type Component  Comprises of a Driver and Compressor  Four Basic types – Reciprocating Engine – Reciprocating Compressor Gas Turbine – Centrifugal Compressor Reciprocating Engine – Centrifugal Compressor Gas Turbine – Reciprocating Compressor

13. Compression Unit - Design  Different models under each type  Properties can be grouped meaningfully – Simulation Data, Operational Data, Manufacturer’s Data  Type and model name can be chosen at run time.  New models can be created and stored in the database

14. Compression Units-Snap Shot

15. Database Design

16. Adaptations  Customized UserObject for each component  Customized method to draw property panel  Provision to group properties meaningfully

17. GUI- Parallel Simulator  Connection is through sockets  Two separate threads are used to avoid GUI freezing  SimulatorClient – send user commands  SimulatorDataClient – get data and status

18. GUI-Parallel Simulator

19. GUI to Parallel Simulator-Snap Shot

20. GUI-Sequential Simulator  Communication is through text files in ASCII format  Input text file contains graph data  Output text file contains simulation data  Option to set global parameters available for input text file.

21. GUI-Sequential Simulator  GraphParser – Input text file generator  Covert.vps to.txt

22. Sequential Simulator - GUI  The Sequential Simulator generates output in standard text format.  The text file is parsed by the GUI to create a live simulation effect  Simulation is the same as replay

23. Sequential Simulator - GUI

24. GUI to Simulators - Supported Features  Simulate (Only in Parallel version)  Replay  Stop  Pause / Resume  Step / Skip Forward  Step / Skip Backward

25. Class Diagram

26. User Feedback  “The GUI application fully implements these features and let users construct a natural gas pipeline system via drag-and-drop. The interface is very friendly. It can send requests to the server (simulator) and display the results back from the server in real- time. In the future, more components may be supported. The display of the results may be improved. In a word, the GUI is excellent.” - Liubo Chen, Programmer – Parallel Simulator  “The GUI for the VPST is a very useful tool for the user to create any pipeline network and run the simulation process. The GUI in its present form contains all the basic components that a Pipeline network comprises off. - Ravi Kiran Addanki, Programmer – Sequential Simulator

27. Conclusion  The new requirements have been satisfied  The basic software has been adapted to meet the complex demands  The tool is fully functional with minimum system requirements
