class ogstools.propertylib.Property

Bases: object

Represent a generic mesh property.

func()

The function to be applied on the data. .. seealso:: transform()

Parameters:

vals (T) –

Return type:

T

mesh_dependent: bool = False

If the function to be applied is dependent on the mesh itself

process_with_units: bool = False

If true, apply the function on values with units.

cmap: Colormap | str = 'coolwarm'

Colormap to use for plotting.

bilinear_cmap: bool = False

Should this property be displayed with a bilinear cmap?

categoric: bool = False

Does this property only have categoric values?

property type_name: str

replace(**changes)

Create a new Property object with modified attributes.

Be aware that there is no type check safety here. So make sure, the new attributes and values are correct.

Parameters:

• changes (Any) – Attributes to be changed.

• self (Property) –

Returns:

A copy of the Property with changed attributes.

Return type:

Property

__init__(data_name, data_unit='', output_unit='', output_name='', mask='', func=<function identity>, mesh_dependent=False, process_with_units=False, cmap='coolwarm', bilinear_cmap=False, categoric=False)

Parameters:

• data_name (str) –

• data_unit (str) –

• output_unit (str) –

• output_name (str) –

• mask (str) –

• func (Callable) –

• mesh_dependent (bool) –

classmethod from_property(new_property, **changes)

Create a new Property object with modified attributes.

Parameters:

• new_property (Property) –

• changes (Any) –

transform(data, strip_unit=True)

Return the transformed data values.

Converts the data from data_unit to output_unit and applies the transformation function of this property. The result is returned by default without units. if strip_unit is False, a quantity is returned.

Note: If self.mesh_dependent is True, self.func is applied directly to the mesh. Otherwise, it is determined by self.process_with_units if the data is passed to the function with units (i.e. as a pint quantity) or without.

Parameters:

• data (int | float | ndarray | UnstructuredGrid | Sequence) –

• strip_unit (bool) –

Return type:

ndarray

get_output_unit()

Get the output unit.

returns: The output unit.

Return type:

str

property difference: Property

returns: A property relating to differences in this quantity.

is_mask()

Check if the property is a mask.

Returns:

True if the property is a mask, False otherwise.

Return type:

bool

get_mask()

Returns:

A property representing this properties mask.

Return type:

Property

property magnitude: Property

mask_used(mesh)

Check whether the mesh contains the mask of this property.

Parameters:

mesh (UnstructuredGrid) –

Return type:

bool

get_label()

Creates property label in format ‘property_name / property_unit’

Return type:

str
