Question #285260 on Yade changed: https://answers.launchpad.net/yade/+question/285260
Jan Stránský proposed the following answer: Hello Behzad, if the model is unstable, it is usually a problem of time step. What happens if you decrease the time step? With the "stiffness" approach, would you get different forces / moments then in "viscoelastic" approach? If so, why not to change the computation directly in the "viscoelastic" approach? cheers Jan 2016-03-02 21:47 GMT+01:00 behzad <[email protected]>: > Question #285260 on Yade changed: > https://answers.launchpad.net/yade/+question/285260 > > behzad posted a new comment: > > The intended model is Burger's model.
