pyfem.util.BaseModule module

class BaseModule(props)[source]

Bases: object

type
def get_nested_attr(obj, attr_path, default=None):

“”” Access a nested attribute in an object hierarchy.

Parameters: - obj: The base object - attr_path: A string of dot-separated attribute names (e.g., “bar.foo.y”) - default: The value to return if any attribute in the chain doesn’t exist

Returns: - The value of the nested attribute, or the default if any attribute is missing “”” try:

for attr in attr_path.split(‘.’):

obj = getattr(obj, attr)

return obj

except AttributeError:

return default

# Example usage: # Assuming x.bar.foo.y exists value = get_nested_attr(x, “bar.foo.y”, default=”Attribute not found”) print(value)

pyfem.util.itemList module

class itemList[source]

Bases: dict

Class to construct a list of items that have a coninuous local number, and a global ID.

add(ID: int, item)[source]

Adds an item with an ID to the list. This item will be stored in the list.

Parameters:

  • ID (int) – the ID of the item to be stored.

  • item – the value(s) of the item to be stored.

get(IDs)[source]

Returns the index / indices of an ID or list of IDs of items in the list.

Parameters:

  • IDs (list[int]|int,optional) – the ID/IDs. If ommited, a list with all indces

  • returned. (will be)

Returns:

a list with the indices. In the case of a single ID, this list has length 1.

Return type:

list[int]

getIndices(IDs: list[int] | int = -1) → list[int][source]

Returns the index / indices of an ID or list of IDs of items in the list.

Parameters:

  • IDs (list[int]|int,optional) – the ID/IDs. If ommited, a list with all indces

  • returned. (will be)

Returns:

a list with the indices. In the case of a single ID, this list has length 1.

Return type:

list[int]

findID(index: int) → int[source]

Returns the ID of an index in the list.

Parameters:

index (int) – the index of the item

Returns:

the ID of the item

Return type:

int

pyfem.util.kinematics module

class Kinematics(nDim: int, nStr: int)[source]

Bases: object

Class that contains the kinematic state of a material point, i.e. strain and deformation gradient.

Parameters:

  • nDim (int) – the number of spatial dimensions of the problem (2 or 3)

  • nStr (int) – the number of strain components (2, 3 or 6)

pyfem.util.logger module

setLogger(props: dict)[source]

Creates a logger for the current analysis with a given format and level.

Parameters:

props (dict) – A dictionary containing the input file of the problem.

Returns:

an instance of the logger.

Return type:

logger

getLogger()[source]

Function that returns an instance of the active logger.

Parameters:

None

Returnslogger: an instance of the active logger.

pyfem.util.plotUtils module

plotCurve(output: ndarray) → None[source]

Plots a curve based on the given output data points.

Parameters:

output (List[Tuple[float, float]]) – A list of (x, y) data points to plot.

Returns:

None

plotTime(t: float) → str[source]

Formats a given time duration into a human-readable string.

Parameters:

t (float) – Time duration in seconds.

Returns:

A formatted string representing the time in seconds, minutes, or hours.
