Node

class itasca.sel.node.Node

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

attach() → float.

Get the attachment condition of a node (true = attached to the grid).

bond() → float.

Get the state of the bond between the element node and host rock/ soil (1 = intact, 2 = broken, 3 = none).

collection() → float.

Get the ID number of a node collection from a given node.

dis() → vec.

Get the node node dis (vector).

dis_x() → float.

Get the x-component of the node node dis.

dis_y() → float.

Get the y-component of the node node dis.

dis_z() → float.

Get the z-component of the node node dis.

extra(slot: int) → any.

Get the node extra data in the given slot.

fix() → int.

Get the fixity indicator of the node (false = not fixed (default); true = fixed).

force() → vec.

Get the node node forcce (vector).

force_app() → vec.

Get the node node applied force (vector).

force_app_x() → float.

Get the x-component of the node node applied force.

force_app_y() → float.

Get the y-component of the node node applied force.

force_app_z() → float.

Get the z-component of the node node applied force.

force_shear() → float.

Get the shear force.

force_x() → float.

Get the x-component of the node node forcce.

force_y() → float.

Get the y-component of the node node forcce.

force_z() → float.

Get the z-component of the node node forcce.

group([slot: str or int]) → str.

Get the node 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 node. 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 node is part of. The keys of the dictionary are the slot names and the values are the group names.

id() → int.

Get the node id.

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

Test if the node 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() → float.

Get the index (offset) of a node.

length() → float.

Get the length associated with a beam or cable node (half of the average length of connected elements).

mass() → float.

Get the node mass.

matnum() → int.

Get the material number assigned to a node.

pos() → vec.

Get the node node position (vector).

pos_x() → float.

Get the x-component of the node node position.

pos_y() → float.

Get the y-component of the node node position.

pos_z() → float.

Get the z-component of the node node position.

set_attach(bool) → None.

Set the attachment condition of a node (true = attached to the grid).

set_bond(float) → None.

Set the state of the bond between the element node and host rock/ soil (1 = intact, 2 = broken, 3 = none).

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

Set the node extra data in the given slot.

set_fix(int) → None.

Set the fixity indicator of the node (false = not fixed (default); true = fixed).

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

Set the node group name in a given slot.

set_matnum(int) → None.

Set the material number assigned to a node.

set_vel(value: vec) → None.

Set the node node velocity (vector).

set_vel_x(value: float) → None.

Set the x-component of the node node velocity.

set_vel_y(value: float) → None.

Set the y-component of the node node velocity.

set_vel_z(value: float) → None.

Set the z-component of the node node velocity.

valid() → bool.

Returns True if this node is live.

vel() → vec.

Get the node node velocity (vector).

vel_x() → float.

Get the x-component of the node node velocity.

vel_y() → float.

Get the y-component of the node node velocity.

vel_z() → float.

Get the z-component of the node node velocity.
