Classes

TurbomoleHessian()

class scine_puffin.jobs.turbomole_hessian.TurbomoleHessian

A job generating a Hessian and derived data for a single structure.

Order Name

turbomole_hessian

Optional Settings

Optional settings are read from the settings field, which is part of any Calculation stored in a SCINE Database. Possible settings for this job are:

self_consistence_criterionfloat

The self consistence criterion corresponding to the maximum energy change between two SCF cycles resulting in convergence. Default value ist 1E-6.

cartesian_constraintsList[int]

A list of atom indices of the atoms which positions will be constrained during the optimization.

max_scf_iterationsint

The number of allowed SCF cycles until convergence. Default value is 30.

transform_coordinatesbool

Switch to transform the input coordinates from redundant internal to cartesian coordinates. Setting this value to True and hence performing the calculation in Cartesian coordinates is helpful in rare occasions where the calculation with redundant internal coordinates fails. The optimization will take more time but is more likely to end successfully. The default is True.

scf_dampingbool

Increases damping during the SCF by modifying the $scfdamp parameter in the control file. The default is False.

scf_orbitalshiftfloat

Shifts virtual orbital energies upwards. Default value is 0.1.

calculate_loewdin_chargesbool

Calculates the Loewdin partial charges. The default is False.

spin_modestr

Sets the spin mode. If no spin mode is set, Turbomole’s default for the corresponding system is chosen. Options are: restricted, unrestricted.

Required Packages

• SCINE: Database (present by default)

• SCINE: Utils (present by default)

• The Turbomole program has to be available

Generated Data

If successful the following data will be generated and added to the database:

Properties

The hessian and the electronic_energy associated with the structure. atomic_charges for all atoms, if requested

archive(archive: str) → None

Archives all files existent in the job’s directory into tarball named with the job’s ID. The tarball is then moved to the given destination.

Parameters:

archivestr

The path to move the resulting tarball to.

capture_raw_output() → Tuple[str, str]

Tries to capture the raw output of the calculation context and save it in the raw_output field of the configured calculation. This should never throw.

Notes

• Requires run configuration

classmethod check_configuration(instance: T) → typing_extensions.TypeGuard[T]

static check_duplicate_property(structure: db.Structure, properties: db.Collection, property_name: str, model: db.Model) → db.ID | bool

Checks for a property that is an exact match for the one queried here. Exact match meaning that key and model both are matches.

Parameters:

propertiesdb.Collection (Scine::Database::Collection)

The collection housing all properties.

property_namestr

The name (key) of the queried property, e.g. electronic_energy.

modeldb.Model (Scine::Database::Model)

The model used in the calculation that resulted in this property.

structuredb.Structure (Scine::Database::Structure)

The structure to be checked in. The structure has to be linked to its collection.

Returns:

IDdb.ID (Scine::Database::ID)

Returns False if there is no existing property like the one queried or the ID of the first duplicate.

clear() → None

Clears the directory in which the job was run.

complete_job() → None

Saves the executing Puffin, changes status to db.Status.COMPLETE.

config: Configuration

configure_run(manager: db.Manager, calculation: db.Calculation, config: Configuration) → None

Configures a job for a given Calculation to do tasks in the run function

Parameters:

managerdb.Manager (Scine::Database::Manager)

The manager of the database holding all collections

calculationdb.Calculation (Scine::Database::Calculation)

The calculation to be performed

configConfiguration

The configuration of the Puffin doing the job

execute_hessian_calculation(job: db.Job) → None

fail_job() → None

Saves the executing Puffin, changes status to db.Status.FAILED.

failed_file() → str

Returns the path to the file indicating a failed calculation, None if job has not been prepared

postprocess_calculation_context() → bool

Postprocesses a calculation context, pushing all errors and comments.

Returns:

True if the job succeeded, False otherwise.

prepare(job_dir: str, id: db.ID) → None

Prepares the actual job. This function has to be implemented by any job that shall be added to Puffins job portfolio.

Parameters:

job_dirstr

The path to the directory in which all jobs are executed.

iddb.ID (Scine::Database::ID)

The calculation that triggered the execution of this job.

prepare_calculation(structure: db.Structure, calculation_settings: utils.ValueCollection, model: db.Model, job: db.Job) → None

read_hessian_matrix(natoms: int) → ndarray

static required_programs() → List[str]

See Job.required_programs()

run(manager: db.Manager, calculation: db.Calculation, config: Configuration) → bool

See Job.run()

stderr_path: str = 'stderr'

stdout_path: str = 'stdout'

store_property(properties: db.Collection, property_name: str, property_type: str, data: Any, model: db.Model, calculation: db.Calculation, structure: db.Structure, replace: bool = True) → db.Property | None

Adds a single property into the database, connecting it with a given structure and calculation (it’s results section) and also

Parameters:

propertiesdb.Collection (Scine::Database::Collection)

The collection housing all properties.

property_namestr

The name (key) of the new property, e.g. electronic_energy.

property_typestr

The type of property to be added, e.g. NumberProperty.

dataAny (According to ‘property_type’)

The data to be stored in the property, the type of this object is dependent on the type of property requested. A NumberProperty will require a float, a VectorProperty will require a List[float], etc.

modeldb.Model (Scine::Database::Model)

The model used in the calculation that resulted in this property.

calculationdb.Calculation (Scine::Database::Calculation)

The calculation that resulted in this property. The calculation has to be linked to its collection.

structuredb.Structure (Scine::Database::Structure)

The structure for which the property is to be added. The properties field of the structure will receive an additional entry, or have an entry replaced, based on the options given to this function. The structure has to be linked to its collection.

replacebool

If true, replaces an existing property (identical name and model) with the new one. This option is true by default. If false, doesnothing in the previous case, and returns None

Returns:

propertyDerived of db.Property (Scine::Database::Property)

The property, a derived class of db.Property, linked to the properties’ collection, or None if no property was generated due to duplication.

success_file() → str

Returns the path to the file indicating a successful calculation, empty string if job has not been prepared

verify_connection() → None

Verifies the connection to the database. Returns only if a connection is established, if it is not, the function will attempt to generate a connection every 10 seconds, indefinitely.
