Dear @youyunxu I am unsure what you mean by get them by hand? Those are the formulas that are currently used in the software. It is possible that very small modifications were made to the contact model between the Lethe-DEM paper and the current implementation. Our current implementation is tested on multiple benchmark including normal contact and contacts at an angle. See the following two examples: Don't hesitate if you have any more questions |

Hi,
I'm new to lethe. I want to know how to get the figure 10 and 11 in "Lethe-DEM : An open-source parallel discrete element
solver with load balancing". When I tried to use nonlinear viscoelastic model to calculate by hand, it seems different with the figures.
Here are the figures in document:
Many thanks!
Xu
