ekinstate_t Class Reference

#include <gromacs/mdtypes/state.h>

Description

Struct used for checkpointing only.

This struct would not be required with unlimited precision. But because of limited precision, the COM motion removal implementation can cause the kinetic energy in the MD loop to differ by a few bits from the kinetic energy one would determine from state.v.

Public Attributes
