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.
