fix enforce 2D

hi all,

Instead of using fix enforce 2D if I run a 3D simulation and by using fix setforce make fz=0…will it be the same?

You don’t say what you are trying to do.

There are various fixes that alter forces,

e.g. fix setforce, fix planefore, fix lineforce.

Particle positions are also affected by their

velocity and whether you time integrate them
or not.
