New BBP Validation Package

This page outlines the process to create a new BBP validation package and use it to produce CyberShake goodness-of-fit results.

Create BBP Validation Package

1. Copy over an already-existing validation package in $BBP_VAL_DIR.
2. Copy the .src file and the .stl file that were used for the validation simulation.
3. Edit the validation_config.txt file, if needed. Possibly modify EVENT_VELOCITY_MODEL, P_CODEBASE_ALL_source, and P_CODEBASE_ALL_stations.
4. Create the .acc files. There should be 1 file per station per component with the filename <station>_<comp>.acc. These files use the following format:

   Rotated Accelerogram to <direction>
   H1 for rotation: <station name> <original angle 1>
   H2 for rotation: <station name> <original angle 2>
   rotation angle - n/a 
   Acceleration in g
   <npts>    <dt>    NPTS, DT
   <values, 6 per row in %.6e format>
   

   You can use the script on Summit in ~callag/scripts/convert_bbp_to_acc.py to convert an acceleration BBP file into 3 .acc files.

Perform goodness-of-fit with CyberShake results

1. Create empty simulation directory tree.
2. Copy CyberShake *.vel.bbp and *.acc.bbp files to the outdata directory.
3. Run the BBP, but skip all simulation stages and start with the plot_map module.
