New question #683405 on Yade: https://answers.launchpad.net/yade/+question/683405
Dear all, until now, I used Yade 2019.01a for my computations. Recently, I also downloaded and installed the current version from gitlab. When I compare the results obtained from both versions, I see (small) differences. I’m a bit worried, because I do not see such differences between Yade 2018.02b and Yade 2019.01a. An example for the obtained differences can be seen in the 03-oedometric-test.py script. I added “seed=1” in the makeCloud command and obtain identical initial positions for the spheres (wrt. yade version). The particles settle under gravity. When the unbalanced force is below 0.1, a plate is inserted for compression. The position of the plate is above the highest sphere in the packing and already here there are differences (note: I changed the PyRunner iterPeriod for a better comparison: PyRunner(command='checkUnbalanced()',iterPeriod=100,label='checker') ) #add plate at position: 0.549239607153 at iteration: 10300 # Yade 2018.02b #add plate at position: 0.549239607153 at iteration: 10300 # Yade 2019.01a #add plate at position: 0.575951497648 at iteration: 9800# yade gitlab compiled with Python 2 #add plate at position: 0.5759514976482029 at iteration: 9800# yade gitlab compiled with Python 3 For backward compatibility, I think it’s worth investigating, what causes these changes. Do you agree? Do you have any suggestion, how I can track these changes down?
