analyze_pickle module

Analyze pickled data demo.

Usage:

This demo loads a pickled reduced model, solves for random parameters, estimates the reduction errors and then visualizes these estimates. If the detailed model and the reductor are also provided, the estimated error is visualized in comparison to the real reduction error.

The needed data files are created by the thermal block demo, by setting the ‘–pickle’ option.

Arguments:

REDUCED_DATA File containing the pickled reduced model.

SAMPLES Number of parameter samples to test with.

Options:

--detailed=DETAILED_DATA

File containing the high-dimensional model and the reductor.

thermalblock_simple module

Simplified version of the thermalblock demo.

Usage:

thermalblock_simple.py MODEL ALG SNAPSHOTS RBSIZE TEST

Arguments:

MODEL High-dimensional model (pymor, fenics, ngsolve, pymor-text). ALG The model reduction algorithm to use (naive, greedy, adaptive_greedy, pod).

SNAPSHOTS naive: ignored

greedy/pod: Number of training_set parameters per block

(in total SNAPSHOTS^(XBLOCKS * YBLOCKS) parameters).

adaptive_greedy: size of validation set.

RBSIZE Size of the reduced basis. TEST Number of parameters for stochastic error estimation.
