Liner

class itasca.sel.liner.Liner

Objects of this type should not be created (instantiated) directly in Python. Use the module functions that return instances of this type.

area() → float.

Get the area of the liner.

extra(slot: int) → any.

Get the liner extra data in the given slot.

face() → face_ptr.

Get the attached face.

fiber_max() → float.

Get the maximum outer fiber stress.

fiber_min() → float.

Get the minimum outer fiber stress.

group([slot: str or int]) → str.

Get the liner group name in a given slot.

group_remove(group_name: str or int[, slot: str or int]) → bool.

Remove from the given group from all group slots of the liner. One argument of type string, giving the group name, is required. The return value is a bool which is True if the group was removed from any slot, otherwise False.

groups() → {slot: group_name}.

Get a dictionary describing which groups this liner is part of. The keys of the dictionary are the slot names and the values are the group names.

id() → int.

Get the liner id.

in_group(group_name: str or int[, slot: str or int]) → bool.

Test if the liner is part of a given group. If the optional argument slot is given, only that slot is searched. Otherwise, all group slots are searched.

index() → int.

Get the index (offset) of the liner element.

matnum() → float.

Get the material number assigned to a liner.

membrane_max() → float.

Get the maximum membrane stress.

membrane_min() → float.

Get the minimum membrane stress.

moment() → vec.

Get the liner liner moment (vector).

moment_max() → float.

Get the maximum bending moment.

moment_min() → float.

Get the minimum bending moment.

moment_x() → float.

Get the x-component of the liner liner moment.

moment_y() → float.

Get the y-component of the liner liner moment.

moment_z() → float.

Get the z-component of the liner liner moment.

node(int) → node_ptr.

Get the a node of a liner face (input {0, 1, 2} for the first, second, or third node of the face, respectively).

normal() → vec.

Get the liner liner normal (vector).

normal_stiffness() → float.

Get the normal stiffness (force/displacement) of the interface between the liner element and the rock/soil.

normal_strength() → float.

Get the normal (tensile) strength of the interface between the liner element and the rock/soil.

normal_x() → float.

Get the x-component of the liner liner normal.

normal_y() → float.

Get the y-component of the liner liner normal.

normal_z() → float.

Get the z-component of the liner liner normal.

poiss() → float.

Get Poisson’s ratio.

pos() → vec.

Get the liner liner position (vector).

pos_x() → float.

Get the x-component of the liner liner position.

pos_y() → float.

Get the y-component of the liner liner position.

pos_z() → float.

Get the z-component of the liner liner position.

set_extra(slot: int, value: any) → None.

Set the liner extra data in the given slot.

set_group(group_name: str or int[, slot: str or int]) → None.

Set the liner group name in a given slot.

shear_cohesion() → float.

Get the cohesion at the interface of the liner element and the rock/soil.

shear_friction() → float.

Get the friction angle (in degrees) of the interface of the liner element and the soil/rock.

shear_stiffness() → float.

Get the shear stiffness (Force / displacement) at the interface between the liner element and the rock/soil.

stress() → vec.

Get the liner liner stress (vector).

stress_x() → float.

Get the x-component of the liner liner stress.

stress_y() → float.

Get the y-component of the liner liner stress.

stress_z() → float.

Get the z-component of the liner liner stress.

thermalexp() → float.

Get thermal expansion coefficient.

thickness() → float.

Get liner thickness.

valid() → bool.

Returns True if this liner is live.

young() → float.

Get Young’s modulus.
