Validation of Binary Workflow

In order to validate the binary workflow we have followed two steps:

• Verify that HF produced with the text workflow is exactly the same as the one produced by the binary workflow at the waveform level
  
  • They use the same Fortran code so the waveforms should match
• BB verification also occurs on the waveforms. There are two stages, as some code has been ported to Python from C:
  
  • Without site amplification ie. we use vs = 500 for everything.
  • Include the site amplification and verify once again.

Results

HF

For random locations, the HF accelerations are visually close. Also, when computing the RMS (Root-Mean squared) error, we get very small discrepancy. For example:

Location WAI:

For this location we have the RMS per component of:

BB

If we start with the same LF and same HF, we should arrive to exactly the same BB acceleration waveforms, this with and without site amplification. Once again, I have repeated the previous steps and found out that we have a perfect matching of waveforms:

Location CCH2:

And the values of the RMS for that location per component are:
