Signature¶

def sdynpy.coordinate_array(node=None, direction=None, structured_array=None, string_array=None, force_broadcast=False)

Creates a coordinate array that specify degrees of freedom.

Creates an array of coordinates that specify degrees of freedom in a test or analysis. Coordinate arrays can be created using a numpy structured array or two arrays for node and direction. Multidimensional arrays can be used.

Parameters¶

• node : ndarray Integer array corresponding to the node ids of the coordinates. Input will be cast to an integer (i.e. 2.0 -> 2, 1.9 -> 1)

• direction : ndarray Direction corresponding to the coordinate. If a string is passed, it must consist of a direction (RX, RY, RZ, X, Y, Z) and whether or not it is positive or negative (+ or -). If no positive or negative value is given, then positive will be assumed.

• structured_array : ndarray (structured) Alternatively to node and direction, a single numpy structured array can be passed, which should have names [‘node’,‘direction’]

• string_array : ndarray Alternatively to node and direction, a single numpy string array can be passed into the function, which will be parsed to create the data.

• force_broadcast : bool, optional Return all combinations of nodes and directions regardless of their shapes. This will return a flattened array

Returns¶

• coordinate_array : CoordinateArray
