I am a Third year engineering student working on an aluminium honeycomb Impact Attenuator for my FS/FSAE team

 

When I first started working on it in Ls Prepost it didn't give any issue beyond a long loading time for it to appear in software up until I tried applying my mesh on it. Then it started to not respond and force me to close prepost.

 

Then after that every subsequent time I tried to load the STEP file my Impact attenuator is in, prepost doesn't respond and I can't get beyond that point?

 

Is there anyway to fix this?

Which version of LSPP are you using? Can you upgrade to the latest we have: Index

My university computers have LS Prepost 2025 R2 V4.13.2

Attached is proof and also my Impact Attenuator project when I intially was working on it before the subsequent times where the software doesn't work
as i tried to load in the STEP file containing it

Thanks for confirming, this is almost an year old now. If you see, the build date is 10 Jun 2025. What I shared in the above link is built on 12th May 2026. The reason I ask to update is, if this issue is related to any previous BUG, it could have been fixed in the latest version.

Please try with the latest LSPP version and let me know. Thanks!
