Enumeration Type Documentation

enum Channel : int

strong

The channels that define with their COM the compartment boundaries in CompEL setups.

In principle one could also use modified setups with more than two channels.

enum DhDlDerivativeCalculation : int

strong

dhdl_derivatives selection \

NOTE: YES is the first one. Do NOT interpret this one as a gmx_bool Why was this done this way, just .........

enum EnsembleTemperatureSetting : int

Whether and what kind of ensemble temperature we have for the system.

Enumerator
Constant	There is no ensemble temperature available for the system.
Variable	The ensemble temperature is fixed over time.
Auto	The ensemble temperature varies over time.
Count	Auto setting for grompp, should not be present in tpr and mdrun.

enum FreeEnergyPerturbationType : int

strong

Free energy perturbation type.

SlowGrowth	then the states change monotonically throughout the simulation
Expanded	then expanded ensemble simulations are occurring

enum FreeEnergyPrintEnergy : int

strong

What to print for free energy calculations.

Printing the energy to the free energy dhdl file. Yes is an alias to Total, and will be converted in readir, so we never have to account for it in code.

enum IntegrationAlgorithm : int

strong

Integrator algorithm.

eiSD2 has been removed, but we keep a renamed enum entry, so we can refuse to do MD with such .tpr files. eiVV is normal velocity verlet eiVVAK uses 1/2*(KE(t-dt/2)+KE(t+dt/2)) as the kinetic energy, and the half step kinetic energy for temperature control

enum InteractionModifiers : int

strong

Coulomb / VdW interaction modifiers.

grompp replaces eintmodPOTSHIFT_VERLET_UNSUPPORTED by eintmodPOTSHIFT. Exactcutoff is only used by Reaction-field-zero, and is not user-selectable.

enum KernelSoftcoreType : int

strong

soft-core function as parameter to the nb-fep kernel/14-interaction.\

Distinguishes between soft-core functions internally. This is different from SoftcoreType in that it offers 'None' which is not exposed to the user.

enum LambdaMoveCalculation : int

Enumerator
No	don't calculate move
Metropolis	using the Metropolis criteria, and 50% up and down
Barker	using the Barker criteria, and 50% up and down

enum LambdaWeightWillReachEquilibrium : int

strong

How we decide whether weights have reached equilibrium.

No	never stop, weights keep going
Yes	fix the weights from the beginning; no movement
WLDelta	stop when the WL-delta falls below a certain level
NumAtLambda	stop when we have a certain number of samples at every step
Steps	stop when we've run a certain total number of steps
Samples	stop when we've run a certain total number of samples
Ratio	stop when the ratio of samples (lowest to highest) is sufficiently large

enum NbkernelElecType : int

strong

Types of electrostatics calculations.

Types of electrostatics calculations available inside nonbonded kernels. Note that these do NOT necessarily correspond to the user selections in the MDP file; many interactions for instance map to tabulated kernels.

enum NbkernelVdwType : int

strong

Types of vdw calculations available.

Types of vdw calculations available inside nonbonded kernels. Note that these do NOT necessarily correspond to the user selections in the MDP file; many interactions for instance map to tabulated kernels.

Xyz	Periodic boundaries in all dimensions.
No	No periodic boundaries.
XY	Only two dimensions are periodic.
Screw	Screw.
Unset	The type of PBC is not set or invalid.

enum PressureCoupling : int

strong

Pressure coupling types.

isotropic is an alias for berendsen

Note: Keep Count as the second-to-last entry, and Default as the last entry - this is needed to keep EnumerationWrapper, EnumerationArray and (de)serialization working.

enum SeparateDhdlFile : int

strong

separate_dhdl_file selection

NOTE: YES is the first one. Do NOT interpret this one as a gmx_bool Why was this done this way, just .........

enum SoftcoreType : int

strong

soft-core function \

Distinguishes between soft-core functions in the input.

enum SolventModel : int

strong

Solvent model.

Distinguishes classical water types with 3 or 4 particles

enum SwapGroupSplittingType : int

strong

Swap group splitting type.

These are just the fixed groups we need for any setup. In t_swap's grp entry after that follows the variable number of swap groups.

enum SwapType : int

strong

Direction along which ion/water swaps happen.

Part of "Computational Electrophysiology" (CompEL) setups

enum TemperatureCoupling : int

strong

Temperature coupling type.

yes is an alias for berendsen

Note: Keep Count as the second-to-last entry, and Default as the last entry - this is needed to keep EnumerationWrapper, EnumerationArray and (de)serialization working.

Function Documentation

const char* enum_name	(	int	index,
		int	max_index,
		const char *const	names[]
	)

Return a string from a list of strings.

If index if within 0 .. max_index-1 returns the corresponding string or "no name defined" otherwise, in other words this is a range-check that does not crash.

Parameters

[in]	index	The index in the array
[in]	max_index	The length of the array
[in]	names	The array

Returns: the correct string or "no name defined"
