                               Structural

The general node for the "STRUCTURAL" group. This class is described in the C++ file 'strnode.h'. The concerned definition is StructNode.

Instance Methods

__init__(self, c_inst)
The C++ instance reference is supposed to be received in the constructor because this object will represent a MBDyn node, element or reference frame

source code

_get_position(self)
Get the position from the MBDyn node

source code

Numpy array

get_position(self)
Return a copy of the position array.

source code

_get_rotation_matrix(self)
Get the rotation matrix from the MBDyn node

source code

Numpy array

get_rotation_matrix(self)
Return a copy of the rotation matrix array the definition of its local reference frame.

source code

_get_velocity(self)
Get the velocity from the MBDyn node.

source code

Numpy array

get_velocity(self)
Return a copy of the velocity array.

source code

_get_angular_velocity(self)
Get the angular velocity from the MBDyn node.

source code

Numpy array

get_angular_velocity(self)
Return a copy of the angular velocity array.

source code

__repr__(self)
Return the node representation as a string

source code

Inherited from basic_objects.BasicObject: get_label, set_c_inst
