Hi, I launched this script with Yade 2018-04-19.git-79b2edb.
I got the repeated output of "porosity X" with the porosity X-value soon getting negativ, and then decreasing againt until ~ -1e100, then I stopped manually the simulation. I did not get any segmentation fault. Could you clarify the situation, please ? ** Changed in: yade Status: New => Incomplete -- You received this bug notification because you are a member of Yade developers, which is subscribed to Yade. https://bugs.launchpad.net/bugs/1767601 Title: segmentation fault after erasing some particles Status in Yade: Incomplete Bug description: Dear all, I built a simple script according to script-session1.py (B.Chareyre). I tried to erase some particles, it was done without any problem. but after finishing the simulation, as soon as I tried to run more iterations, it showed segmentation fault and quit yade.
