Dear all,
I want to use “fix tfmc” for a simulation cell with periodic boundary condition on two faces along the x-direction, periodic boundary condition on two faces along the z-direction, and shrink-wrapped boundary condition on the two faces normal to the y-direction. Also, I have a free surface on one face along the y-direction and a fixed-block with a thickness of 5 (Å) using “fix spring/self”. Now, please see my questions listed below.
