  1. Overview and Usage of theExcel SINDA Controller for SINDA/FLUINT

  2. API Overview • Microsoft COM-based commands • COM methods allow applications to “call” other applications, similar to a program calling a subroutine • A SINDA Controller (iSINDA) has been created as a COM-based object • Can be addressed directly by third party software such as Excel, Matlab, iSIGHT • Launches SINDA/FLUINT • Enables data exchange and restarts

  3. Excel Launcher Template • iSINDA provides communication between programs • Provides ability to launch SINDA/FLUINT from Excel • Ability to exchange register and processor data with Excel • Allows postprocessing in Excel • return of processor variables and registers back to Excel • ability to query save file for data • XY plotting in Excel • Interface is customizable • “Prebuilt” option allows models to be run without a SINDA/FLUINT license • Version available for Thermal Desktop

  4. Typical Uses • Allow rapid updating and launching of a pre-existing SINDA/FLUINT model • Ability to superimpose model results on a sketch or photo of the actual hardware • Alternate user interface allowing a new SINDA/FLUINT user to easily modify and launch a model without having to navigate the cryptic ASCII file • Can be used to develop a pre-compiled version of the model to run in a license-free mode • To be run by non-technical support personnel • Deliverable for a customer

  5. Basic Usage Interface can be customized by the user

  6. Plot Control Usage

  7. Demo basic interface

  8. Enable COM Interface • The underlying SINDA/FLUINT model must include commands to enable the COM interface • Enable COM in Operations Data • Pause execution of SINDA/FLUINT run to allow update of parameters in Excel (can occur in any logic block) • Send parameters to Excel for postprocessing (Operations Data) CALL COMINIT $ Initiates the API connection $ back to Excel CALL DOWAIT $ Pauses execution, places $ SINDA/FLUINT wait state CALL SETREAL(Twidget, comp.T21) $ Send a real variable to Excel CALL SETINT(Status,Icount) $ Send an integer back to Excel

  9. Sample COM Logic HEADER OPERATIONS BUILD ALL CALL COMINIT $ Initiates the API connection back to Excel ... C make a certain node’s temperature can be examined or set from Excel CALL SETREAL(‘HiTemp’,WING.T14) 100 CONTINUE CALL STEADY CALL DOWAIT C At this point check and set registers in Excel C When we are done we will set the register IMDONE to 1 in Excel IF(IMDONE .NE. 1) GOTO 100

  10. Demo of customized Excel interface

  11. Access Information • Basic Excel Interface is installed with SINDA/FLUINT • Accessible from the start menu • Loop Heat Pipe customized sample is available for download from the web site • www.crtech.com/excelSinda.html • If you need the prebuilt version, please contact us.
