Import CAD file in EDEM V2022.3

jc_794

Dear Altair Community,

I am encountering an issue when trying to import CAD files into EDEM v2022.3. The loading bar gets stuck at 2%, preventing the import from completing. However, the same CAD file imports smoothly in EDEM v2024.1.

I have tried several troubleshooting steps, such as changing the file location to a shorter path, but the issue persists.

I have attached two files to this post for reference. Could you please advise on how to successfully import them in EDEM v2022.3? I need to use this version because I am coupling EDEM with HyperStudy, and it seems that only v2022.3 works well with my EDEMPy post-processing script.

I appreciate any suggestions or insights you may have.

Best regards,
Jipei

Hi Jipei,

This looks like it might be a bug, that is fixed in the latest version. I don't have a specific workaround but you could try a different file format? I would expect STEP or IGES typically to work OK.

Also it seems it's worth updating the script if this is causing some limitations. There are a few format changes required between versions, the typical issue is that some of the older versions specify deck.creatorData and the newer versions require deck.creatorData[0] but there may be some other changes required.

deck.creatorData[0] means reading the data from the EDEM creator at time-step 0, this is because things like particle types and shapes can change if the user stops the simulation at non-zero time point and makes a change to the particle definitions, you can also update the scripts to check all time-steps or last time-step to ensure all particle types are captured, but adding [0] often works OK.

Regards

Stephen
