Nice....how fast is Lethe DEM ..is there study available to compare it with other DEM codes? Thank you

[@lethecfd6431]

The performance is increasing every day as we are always continuously improving the software itself. It is hard to assess if it is much faster or slower than other code as this really depends on the simulation set-up.

​@@lethecfd6431 I will definitely try this code for compression simulations. I am looking for a computationally efficient DEM code that can handle at least 40,000 particles. LIGGGHTS is another option, but it takes a lot of computational time. :)

Nice.* How* fast is Lethe DEM?* Is* there a* study avaliable (...)?
