High-F 14.12 Verification and Validation Exercise
This page collects information about a proposed high frequency verification and validation exercise. Planning started in Dec 2014.
Agreements Needed
- Simulation Volumes
- Rotation Angle
- Projections used
- Points per wavelength used
- Number and location of sites used for ground motion comparison
- La Habra Point Source parameters
- Currently available code capabilities in GPU codes
- small scale heterogeneities
- FDQ
- Plasticity
- dynamic rupture source
- V and V exercise stages - need to be reviiewed and approved
Volume
The four corners are:
