Removed functionality

Group cut-off scheme

The group cut-off scheme has been removed. Several kinds of simulation that depend on it no longer work.

  • Simulations under vacuum conditions are not supported.

  • User supplied tables for short-range nonbonded interactions are not supported.

  • Switched short-range nonbonded interactions with PME are not supported.

  • Membrane embedding is deactivated.

  • QMMM is not supported.

Issue 1852

Generalized reaction-field

This only worked correctly with the group scheme. Note that generalized reaction-field simulations can still be performed using standard reaction field and computing the dielectric constant manually.

gmx anadock

The gmx anadock tool was removed since it does not belong in gromacs (it analyzes AutoDock outputs).

gmx dyndom

The gmx dyndom tool was removed since it does not belong in gromacs (it analyzes DynDom outputs).

gmx morph

The gmx morph tool was removed since it yields non-physical structures that can easily be done by a script.

gmx mdrun -gcom

This feature sometimes overrode the effects of various .mdp settings in a way that was difficult to understand and report. A user who wants to do communication between PP ranks less often should choose their nst* mdp options accordingly.
