Autocorrelation of Nested Cylinder Hydrodynamic Fields

Code Documentation

Generates a heatmap plot of the 2D auto-cross-correlation-coefficients across hydrodynamic fields, averaged across multiple samples

Can plot all fields (-F All) or some selected fields (-F str str)

Fixed key (-XK) specifies what subset of data to consider

‘None’ can be passed to consider any input with no restrictions
For coupon data, fixed keys must be in the form ‘tpl###’ or ‘idx#####’
For nested cylinder data, fixed keys must be in the form ‘id####’ or ‘idx#####’

Exports correlation coeffients as a pandas-readable .csv

Samples can be preselected and listed in a .txt file (-FL filepath) OR

Number of samples can be specified and a random selection satisfying the fixed key requirement will be made (-FL MAKE -NS #)

Input Line for Coupon Data: python field_autocorr.py -E coupon -ID ../examples/tf_coupon/data/ -F All -S ../examples/tf_coupon/figures/

Input Line for Nested Cylinder Data: python field_autocorr.py -E nestedcylinder -ID ../examples/pyt_nestedcyl/data/ -F All -S ../examples/pyt_nestedcyl/figures/

Arguments

Generates a matrix of the scalar 2D auto-cross-correlation-coefficient between hydrodymanic fields

Named Arguments

--EXPERIMENT, -E

Possible choices: coupon, nestedcylinder

Which experiment the model was trained on

Default: “coupon”

--INPUT_DIR, -ID

Directory path where all of the .npz files are stored

Default: “../examples/tf_coupon/data/”

--FILE_LIST, -FL

The .txt file containing a list of .npz file paths; use “MAKE” to generate a file list given an input directory (passed with -ID) and a number of samples (passed with -NS).

Default: “MAKE”

--PRINT_FIELDS, -PF

Prints list of hydrodynamic/radiographic fields present in a given .npz file (passed with -IN) and quits program

Default: False

--PRINT_KEYS, -PK

Prints list of choices for the fixed key avialable in a given input dirrectory (passed with -ID) and quits program

Default: False

--PRINT_SAMPLES, -PS

Prints number of samples in a directory (passed with -ID) matching a fixed key (passed with -XK) and quits program

Default: False

--FIELDS, -F

List of fields to be included; pass “none” to use an all-zero field; pass “All” to use all valid fields.

Default: [‘rho’, ‘eqps’, ‘eqps_rate’, ‘eff_stress’, ‘porosity’]

--FIXED_KEY, -XK

The identifying string for some subset of all data samples; pass “None” to consider all samples

Default: “None”

--NUM_SAMPLES, -NS

Number of samples to use; pass “All” to use all samples in a given input dirrectory (passed with -ID)

Default: “All”

--SAVE_FIG, -S

Directory to save the outputs to.

Default: “../examples/tf_coupon/figures/”
