Difference between compute wall/gran and fix wall/gran

Submitted by FelipeL on Wed, 09/13/2017 - 20:08

Hi!

I need to calculate the numbers of contacts between particles and walls, something similar to compute contact/atom, so i tried to determine the overlap on the mesh. My question is what´s the difference between compute wall/gran delta (overlap of the contact) and fix wall/gran contact_area overlap?.

For compute wall/gran delta, i got just one column of data, but for fix wall/gran contact_area overlap, i have 8 columns of diferents information depending on how many f_Id[x] i define.

Where can i check which information f_id[x] is showing?

Any suggestion will be greatly appreciated.

Regards,

Felipe
