1. Please see the in.* file in the folder of lammps/example/shear. If you are not able to find it, please click the following link as a reference.
https://github.com/lammps/lammps/tree/master/examples/shear

From which you can see how the author define the boundary and main body, and how he/she applies the velocity proportionally changed over the domain of interest.

2. Please check out the website below for knowing how to output the strain and stress and so forth.
