Changing EDEM simulator setting without using user interface

Hi everyone,

 

Is there a way to access simulator data and modify them with a text editor or a python code? For example, can change time step and simulation time using a text editor or a python code? 

 

Thanks

    Hi Amir,

     

    Now you can use HDFView to open and edit the EDEM .h5 files manually or use h5py to edit them through python but this is not a supported approach. You can expect setting functionality for many of the deck components to be available in the edempy library in the near future and this will be a supported approach.

     

    Best regards,

    Stefan

    thank you Stefan, looking forward to new updates. Do you have any time estimate on when these new functionalities become available?

    Hi Amir,

    I'll check internally and get back to you on that.

    Best regards,

    Hi,

    On top of what Stefan mentions about EDEMpy, if you specifically want to change the timestep and simulation time for a particular run, you can do that now using EDEM's command line flags, though they won't be saved to the simulation settings.

    If you open a command window and type:

    edem -?

    you will see the various flags that you can use to control other areas of EDEM, particularly those in the Simulator tab. There is a tutorial on using this approach here:
