  • G4-News, 24.04.17, GNS mbH Page 9

    Changes 1.3.0

    Keyword support

    - Problem: Each FE solver has a large amount of keywords. Large effort to write and

    maintain the file parser.

    - Solution: Define an XML file for each FE-solver which describes the syntax of each input card.

    - Data type ( integer, float, text )

    - Data usage ( ID, ID reference, switch )

    - Connections to other keywords

    - Format changes due to version or simulation type

  • G4-News, 24.04.17, GNS mbH Page 22

    Changes 1.3.0

    Presimulation Module- Motivation

    Getting a seat to a different position needs the steps:

    - Adjust the seat position

    - Change the dummy and/or adjust the limb positions

    - Modify the seatbelt

    - Do a presimulation to adjust the seat foam due to the dummy sitting in the seat

    - That has to be done for different seats on different sitting positions ( driver and occupants )

  • G4-News, 24.04.17, GNS mbH Page 23

    Changes 1.3.0

    Presimulation Module- Old solution

    Write a complex session file and stop to let the user do some interaction like setting the seat position.

    Limitations: Due to a limited keyword support in Generator4 user has to edit input deck.

    With more keywords: User has to search for the parameters which affects the presimulation

    No solution how to start the presimulation or get the results to the 'real' simulation

  • G4-News, 24.04.17, GNS mbH Page 24

    Changes 1.3.0

    - New solution

    - Basic idea is from a metal sheet forming process Divide a presimulation in Steps ( when is it happening ) and Actions ( what is happening )

    - Present the Steps for the user in an step by step order

    - Define once what parameters can be set for each Action and show them In the GUI. The user does not need to now what input keywords are affected.

    - Start the Presimulation from Generator4 and see the results after it is finished.

    - Mechanism can be used for all kinds of (Pre)simulations

    - Detailed presentation from Paskal Kauer in the afternoon
