Small Scale Heterogeneities Validation
From SCECpedia
Introduction
We would like to validate that the media with the small-scale heterogeneities that are being generated with the new C code are correct. One way to do this would be to take a look at some plots to see if the generated heterogeneities look correct. We present a few different meshes and plots showing the heterogeneities at various depths, as well as difference plots.
Common parameters:
d = 20
st23 = 5
n1 = 500
n2 = 1000
n3 = 1500
Validation by Hurst Value
In this test, we vary hurst to be either 0.0, 0.2, or 0.4. L1 is held constant at 200m.

Validation by Correlation Length
In this condition, we hold hurst to be a constant 0.2, but vary correlation length to be either 100m, 200m, or 300m.
