Signature¶

def sdynpy.core.sdynpy_shape.rigid_body_error(geometry, rigid_shapes, **rigid_shape_kwargs)

Computes rigid shape error based on geometries

Analytic rigid body shapes are computed from the geometry. The supplied rigid_shapes are then projected through these analytic shapes and a residual is computed by subtracting the projected shapes from the original shapes. This residual is a measure of how “non-rigid” the provided shapes were.

Parameters¶

• geometry : Geometry Geometry from which analytic rigid body shapes will be created

• rigid_shapes : ShapeArray ShapeArray consisting of nominally rigid shapes from which errors are to be computed

• **rigid_shape_kwargs : various Additional keywords that can be passed to the Geometry.rigid_body_shapes method.

Returns¶

• coordinates : CoordinateArray The coordinates corresponding to the output residual array

• residual : np.ndarray Residuals computed by subtracting the provided shapes from those same shapes projected through the analytical rigid body shapes.
