The behavior of the constrained dynamics is controlled by the setup provided in the [cst] section. This section belongs to the {PMFLIB} group.
[cst]
Key | Default value | Type | Description |
fmode | 0 | integer | The mode of constrained dynamics: 0 - the method is disabled 1 - the method is enabled If the method is enabled then at least one constraint should be provided in the {CON} group. The constraint specification is described in CON:Constraints. |
fsample | 500 | integer | Every fsample MD steps, the accumulated data will be printed to the constrained dynamics output file. The name of the output file is provided in the [files] section. |
fplevel | 0 | integer | The level of output printed to the output file. 0 - standard output 1 - only user specified constraints are printed |
frestart | off | logical | Disable/Enable restarting the constrained dynamics simulation from the previous run. The name of the restart file is provided in the [files] section. If the restart is enabled but no restart file exists only warning is raised. |
faccurst | 1000 | integer | After faccurst MD steps, the accumulated data are reseted. |
flambdasolver | 0 | integer | It determines solver of constraint equations. Supported types are: 0 - Newton method 1 - Chord method |
flambdatol | 1.0^-4 | real | Requested tolerance of the solution. The solution is accepted if all lambda correction in the given step will be lower than flambdatol. |
fmaxiter | 50 | integer | Maximum number of iteration that the solver can used to find solution of constraint equations. |
