Hi Anton, you are right, changing the script as follows has the same effect: # -*- coding: utf-8 import subprocess numberTests = 10 for z in range(numberTests): #O.reset() bodies= O.bodies.append(pack.regularHexa(pack.inSphere((Vector3(0.0,0.0,0.0)),0.5),radius=0.01,gap=0)) print number of bodies:, len(O.bodies) for b in bodies: O.bodies.erase(b) cmd = ps -o vsz -p `pgrep yade` | grep -v VSZ process = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True) meminfo = process.communicate()[0].strip() print Yade memory usage: , meminfo, kB cmd = egrep 'MemFree' /proc/meminfo process = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True) meminfo = process.communicate()[0] print meminfo sys.exit(0) -- You received this bug notification because you are a member of Yade developers, which is subscribed to Yade. https://bugs.launchpad.net/bugs/1290194 Title: O.reset() does not free memory Status in Yet Another Dynamic Engine: New Bug description: O.reset() does not free the memory, i.e. if you run a series of simulations in a loop the memory usage is accumulating.

[Yade-dev] [Bug 1290194] Re: O.reset() does not free memory
I can confirm this bug. Some time ago I wrote a (python) script which calls yade for performing a sphere drop with changing parameters. IN this script yade way invoked once and after a sphere drop was finished simulation was reset for the next parameter set. It ended up in about 30.000 parameter combinations that were simulated. This took about 5 days and at the end 128 GB Ram plus the same for Swap file was used... -- You received this bug notification because you are a member of Yade developers, which is subscribed to Yade. https://bugs.launchpad.net/bugs/1290194 Title: O.reset() does not free memory Status in Yet Another Dynamic Engine: New Bug description: O.reset() does not free the memory, i.e. if you run a series of simulations in a loop the memory usage is accumulating.
