Mohr’s Circle Package

This package includes utilities to compute and plot Mohr’s Circles using the Python View from Paraview.

geos_posp.visu.mohrCircles.functionsMohrCircle module

functionsMohrCircle module provides a set of utilities to instanciate Mohr’s circles and Mohr-Coulomb failure envelope.

geos_posp.visu.mohrCircles.functionsMohrCircle.buildPythonViewScript(dir_path, mohrCircles, rockCohesion, frictionAngle, userChoices)[source]

Builds the Python script used to launch the Python View.

The script is returned as a string to be then injected in the Python View.

Parameters:

  • dir_path (str) – directory path

  • mohrCircles (list[MohrCircle]) – list of MohrCircle objects

  • rockCohesion (float) – rock cohesion (Pa)

  • frictionAngle (float) – friction angle (rad)

  • userChoices (dict[str, Any]) – dictionnary of user plot parameters

Returns:

Complete Python View script.

Return type:

str

geos_posp.visu.mohrCircles.functionsMohrCircle.createMohrCircleAtTimeStep(stressArray, cellIds, timeStep, convention)[source]

Create MohrCircle object(s) at a given time step for all cell ids.

Parameters:

  • stressArray (npt.NDArray[np.float64]) – stress numpy array

  • cellIds (list[str]) – list of cell ids

  • timeStep (str) – time step

  • convention (* True is usual) – convention used for compression.

  • convention

  • convention – Returns:

  • list[MohrCircle] – list of MohrCircle objects.

geos_posp.visu.mohrCircles.functionsMohrCircle.createMohrCirclesFromPrincipalComponents(mohrCircleParams)[source]

Create Mohr’s circle objects from principal components.

Parameters:

  • mohrCircleParams (list[tuple[str, float, float, float]]) – list of Mohr’s

  • parameters (circle)

Returns:

list of Mohr’s circle objects.

Return type:

list[MohrCircle]

geos_posp.visu.mohrCircles.functionsMohrCircle.createMohrCoulombEnvelope(rockCohesion, frictionAngle)[source]

Create MohrCoulomb object from user parameters.

Parameters:

  • rockCohesion (float) – rock cohesion (Pa).

  • frictionAngle (float) – friction angle in radian.

Returns:

MohrCoulomb object.

Return type:

MohrCoulomb

geos_posp.visu.mohrCircles.functionsMohrCircle.findAnnotateTuples(mohrCircle)[source]

Get the values and location of min and max normal stress or Mohr’s circle.

Parameters:

  • mohrCircle (MohrCircle) – input Mohr’s circle

  • maxTau (float) – max shear stress

Returns:

labels and location of labels.

Return type:

tuple[str, str, tuple[float, float], tuple[float, float]]

geos_posp.visu.mohrCircles.functionsMohrCircle.getMohrCircleId(cellId, timeStep)[source]

Get Mohr’s circle ID from cell id and time step.

Parameters:

  • cellId (str) – cell ID

  • timeStep (str) – time step.

Returns:

Mohr’s circle ID

Return type:

str

geos_posp.visu.mohrCircles.plotMohrCircles module

plotMohrCircles module provides a set of functions to plot multiple Mohr’s circles and a failure envelope from a list of MohrCircle and MohrCoulomb objects respectively.

geos_posp.visu.mohrCircles.plotMohrCircles.createMohrCirclesFigure(mohrCircles, mohrCoulomb, userChoices)[source]

Create Mohr’s circle figure.

Parameters:

  • mohrCircles (list[MohrCircle]) – list of MohrCircle objects.

  • mohrCoulomb (MohrCoulomb) – MohrCoulomb object defining the failure

  • envelope.

  • userChoices (dict[str, Any]) – dictionnary to define figure properties.

Returns:

Figure object

Return type:

Figure

geos_posp.visu.mohrCircles.plotMohrCircles.updateTitle(ax, userChoices)[source]

Update title.

Parameters:

  • ax (Axes) – axes object.

  • userChoices (dict[str, Any]) – user parameters.
