Multiple timestep parameters

NAMD allows efficient full electrostatic evaluation through the use of multiple time stepping. The computational aspects of these parameters are discussed in more detail in section 5.2.1.

• MTSAlgorithm $\langle$ MTS algorithm to be used $\rangle$
  Acceptable Values: naive, verletI, verletX
  Default Value: naive
  Description: Specifies the multiple timestep algorithm used to integrate the long range forces. We recommend verletI because of its conservation properties, with stepspercycle set to 4. If Langevin dynamics is used, then verletX might be a better choice. See section 5.2.1 for the differences between these methods.

• longSplitting $\langle$ how should long and short range forces be split? $\rangle$
  Acceptable Values: sharp, xplor, c1
  Default Value: sharp
  Description: Specifies the manner in which the long and short range forces are combined. We recommend using the c1 splitting. See section 5.2.1 for more details.
