Dear Lammps developers,
I have an input file in which I apply a damping force to a set of atoms:
variable fdvar atom mult(0.7,sub(vx,0.001))
compute fd g_pullingblock variable/atom fdvar
fix f3c g_pullingblock addforce c_fd NULL NULL
how can this be done in the new lammps ?
I have seen that the compute variable/atom was deleted but there is no clear description of how can one replace it. I looked here:
The following commands are deleted in this version, since they have been replaced by more general output options: "fix gran/diag", "compute epair/atom", "compute ebond/atom", "compute variable/atom", "compute variable", "compute sum/atom", and "compute attribute/atom".
the link that underlines the "output options" in this sentence is a broken link:
As you can see I am not using the compute/variable for an output.
Please let me know which new command can do this same thing.
