This is an unofficial Gromacs version with additional kernels using a distance dependent dielectric constant. This modification is primarily intended for use with the EEF1-SB implicit solvent force field implemented in Plumed. The implicit solvent is optimized for use with CHARMM36, which is bundled with this Gromacs version.
Use this just like regular Gromacs, but specify userint1 = 1
to activate the distance dependent dielectric constant kernels and set epsilon-r
to the desired factor. This modification is currently only implemented for SIMD and not for GPU kernels.
