Subsampling Methods

Methods used to perform subsampling of simulation runs.

create_reference_subsample(load_path, parts, nr_samples=2000)

Loads the D3plot at load_path, extracts the node coordinates of part 13, returns a random subsample of these nodes

Parameters:

Name	Type	Description	Default
load_path	str	Filepath of the D3plot	required
parts	Sequence[int]	List of parts to be extracted	required
nr_samples		How many nodes are subsampled	2000

Returns:

Name	Type	Description
reference_sample	np.array	Numpy array containing the reference sample
t_total	float	Total time required for subsampling
t_load	float	Time required to load plot
err_msg	str	If an error occurs, a string containing the error is returned instead

remap_random_subsample(load_path, parts, reference_subsample)

Remaps the specified sample onto a new mesh provided by reference subsampl, using knn matching

Parameters:

Name	Type	Description	Default
load_path	str	Filepath of the desired D3plot	required
parts	list	Which parts shall be extracted from the D3plot	required
reference_subsample	np.ndarray	Numpy array containing the reference nodes	required

Returns:

Name	Type	Description
subsampled_displacement	np.ndarray	Subsampled displacement of provided sample
t_total	float	Total time required to perform subsampling
t_load	float	Time required to load D3plot
err_msg	str	If an error occured, a string is returned instead containing the error
