GROMACS version: GROMACS 2024 GROMACS modification: No Hi every one, I want to reproduce some MD simulations performed with NAMD using the same parameters in GROMACS. These simulations in NAMD used a Langevin thermostat. If I want to use the md integrator in GROMACS, which thermostat should I choose? Which thermostat in GROMACS is equivalent to the Langevin thermostat in NAMD? thanks! yn liu ---

The `sd` integrator is a leap-frog integrator with Langevin friction for temperature control. ---

thank you for your answer, I’ll try this integrator.
