3DCS Batch Processor -- how to set up Design of Experiments DOE

219 visualizaciones

Publicado el

The 3DCS Batch Processor is a powerful tool that lets you set up advanced analysis runs through a command-line code.

This lets you run multiple analyses in tandem, or create variant analyses to run during your off time, taking full advantage of your licensing.

  2. 2. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. 3DCS Batch Processor ● What is it? ● What can it do? ● Value of Batch Processor ● Use Cases Data Flow ● Live Demo
  3. 3. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. What is 3DCS Batch Processor? • 3DCS Simulation Engine – AKA: SimuMacro, Analysis Batch Mode • Launched from 3DCS or DOS command line – Supports FEA Compliant and Mechanical Modeler – Consumes additional Analyst license if DOS run, but not if launched from 3DCS • Provided with all 3DCS VA installations
  4. 4. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. What can Batch Processor do? • Run Analysis on a complete 3DCS Model – Simulation, HLM & GeoFactor Supported • Run Analysis based on Move, Tolerance & Measure modifications. – Design of Experiments (DOE) – Tolerance changes – On Off changes – Tolerance Trend Study – Move, Tolerance & Measure changes
  5. 5. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. Value of Batch Processor ● Run analyses overnight -- free up your workstation during business hours ● Run long analyses and have the results waiting for you ● Run multiple models back-to-back to determine optimal configurations
  6. 6. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. Option 1: Run from 3DCS 1. Open 3DCS Model 2. Start Batch Processor 3. Change Settings or Path to output patch 4. “Run” 5. Review Results
  7. 7. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. Option 2: Run from DOS 1. Complete & Save 3DCS Model 2. Start Batch Processor from DOS 3. Review Results Additional license is used
  8. 8. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. Recommended method 1. For a simple run with no changes to inputs or outputs - use Option1 2. When parameters need to be modified in the Script file and/or sending the information to run the analysis on a different computer - use Option2
  9. 9. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. Batch Files Launching the Batch Processor creates these files in the Model’s Directory: 1. Script file - includes command lines that can be activated or deactivated based on the desired outputs, the output format and thread number 2. Batch file - identifies the location for the dcsSimuMacro.exe and executes the steps activated in the dcsRunDoeScript.txt file 3. WTX file - used for calculations; a copy of the model.
  10. 10. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. DOE Files 1. Run Function dcu_doe_form.dll from User DLLs to launch the DOE Setup. 2. Select CSV File Format # 2 in Options to list all types of inputs wanted for the study. 3. Save csv file will create a csv and a wtx file. The Example_doe.csv.xlsx explains all inputs. 1. To obtain the Batch file Run dcsDoeViewer.
  11. 11. Dimensional Control Systems | 2019 All Rights Reserved | Confidential - Do not distribute. Best Practices for DOE 1. Use C:Temp as working directory when transferring the files to another computer. 2. Separate the runs for Simulation, Sensitivity, Geo Factor when working with large models. Rename the Results folder to reflect the type of run then start the next analysis. 3. Keep file names short to make the Script file easier to modify.

How does Batch Processor work? • Normally, in the 3DCS software, you are running the software interactively – Click a button, run the analysis • With Batch Processor… – Analysis is run by command line input – Runs analysis for several models/setups either sequentially or in parallel
