Hi, This is a DEME-related question. It possible might be helpful to other people who use Chrono GPU as well.
I am pretty new to DEM simulations so excuse my ignorance on this topic. I have used the DEME solver to obtain the particle contact information file that includes information such as interacting particles, forces, and contact locations. I have some questions regarding these that I hoped you could help me with. 1- For DEM users, what are some of the most important parameters that can be extracted using the particles' contact information? 2- I have done some reading and have found that particle stresses can be calculated using the contact information as 1/V*sum(x_i*F_i) where x is the contact location and F is the contact force. This is pretty easy to do when you have one file. However, since contact files are outputted at every frame, I was wondering if there is a program that DEM users use to process this data. I realize that ParView is one popular option. I would appreciate it if someone had a good example to share. 3- Visualization. what would be the best way to use/combine the contact data files with the sphere data files (Outputted using *WriteSphereFile )* to better visualize the calculated data? In other words, if I were to process the contact information file in ParaView, what is the best way to render the results along with the sphere data files? Thank you so much for your help in advance, I realize that these might be some basic things that DEM users know how to do. However, I have been reading a lot about this and could not find very good resources regarding these questions. Any good examples with pictures will be so much appreciated. Hope this helps other users who are new to DEM modeling as well. Thank you again, -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
