EDEMpy automated queries

I created a script to run a series of simulations (64 in total) starting from a template deck, which had 3 queries to save the X, Y and Z particle position. However, the queries were not created for the rest of the simulations. Is there a way using EDEMpy to create the queries and extract the data I want without opening each .dem file and exporting the csv file manually?

Thank you.

Hi @Felipegumo95,

If you are running the simulations using the command line options, you have to use the -e flag in order to automatically export the queries after the simulation is done.

You can learn more about the command line flags here:

Okay, but I don't understand how to automatically create the queries for different .dem files before running the simulations.

I did a script to create 64 different .dem files for which I set different combinations of coefficient parameters. For this script I created a template deck using the GUI with the queries I needed. After checking some the new .dem files, none of them have the queries the template deck has.

I ran the simualtions in a HPC via bash, but I didn't include the -e flag as the files didn't have the queries beforehand. I guess my question is how can I instruct via EDEMpy to not only create different a set of .dem files, but additionally that each .dem file includes the queries from the template deck.

Thank you.

The queries are stored in the .dfg file. By default, the .dfg doesn't contain any queries, so when you create a new .dem file you have to create a copy of the original .dfg file (and possibly rename it) in order for the queries to be defined.

Another option is to use the path to the original .dfg file when running the simulations from the command line, like:

"path\to\edem" -c -i "path\to\sim22.dem" -e "path\to\original_file.dfg"
