Dear Lammps users,
I am trying to simulate a liquid flow between two parallel fixed walls. The walls are fixed by "fix setforce 0.0 0.0 0.0" and "velocity set 0.0 0.0 0.0". I was wondering when the walls are fixed, can I consider them as adiabatic walls or they are heat sinks with the constant temperature of zero?
Thank you in advance for your help.
