GROMACS version: 2020.4
GROMACS modification: Yes, interfaced with Plumed 2.6.2
Here post your question
I was trying to run Hamiltonian REMD simulations with Gromacs 2020.4 and Plumed 2.6.2, but the simulations failed. I think the reason is that the flag -multi from mdrun was removed since Gromacs 2019.X, but only kept -multidir, while -multidir does not work properly with -hrex (for Hamiltonian REMD).
I used to run with Gromacs 2018.X, is there a way to solve this problem, or will the developers keep the flag -multi ? Thanks a lot!
All the best,
