Jan Stránský proposed the following answer: > > > Your alternative work but it doesn't resolve my problem because the > external work obtained is underestimated (i compare it with the elastic > energy). > Do you have some values? for example https://github.com/yade/trunk/blob/master/pkg/dem/UniaxialStrainer.cpp#L106 changes the value to half, but if you compute work from it, you should multiply it by 2 again.. Could you also post a script you use? > I tried a second alternative which based on the difference of the total > displacement between iteration "i" and "i+1". > The problem is that in UniaxialStrainer.cpp i can't do this difference > because we can't control the > I tried these lines of code but it doesn't work: > > Real displacement; Real S; > S=axialLength-originalLength; > displacement=(axialLength-originalLength)-S; > I obtained displacement=0. May be this solution is stupid but i don't know > how to do the get the difference in > UniaxialStrainer.cpp > of course :-) displacement=(axialLength-originalLength)-S = (axialLength-originalLength) - (axialLength-originalLength) = 0 for any values of axisLength and originalLength the solution is to store the previous value inside the class cheers Jan -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
