R: Re: Triax - yade-versions

 

I have generated a new Triaxial with the last release. Probably that's the reason as you say (anyway it was a big sample, 4000 balls).

For my graphic problem try to see what happens if you use the parameters you can find on the attached txt file and using the release 1902.
