SCALEE = [real]
Default: SCALEE = 1
Description: This tag specifies the scaling of the energies and forces.
For thermodynamic integration this parameter controls the coupling parameter .
This parameter is only used if SCALEE1.
Usually the thermodynamic integration is carried out from the ideal gas to the liquid state.
If the file DYNMATFULL exists in the calculation directory and SCALEE1, the second order Hessian matrix is added to the force and thermodynamic integration from a harmonic model to a fully interacting system is carried out. Here the Hamiltonian for a certain integration point along the thermodynamic integration pathway is given as
