Small Scale Heterogeneities Validation
From SCECpedia
Jump to navigationJump to searchContents
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.
Plots at surface level
| Matlab Code 0.0 Hurst | C SSH Code 0.0 Hurst | Difference 0.0 Hurst |
| Matlab Code 0.2 Hurst | C SSH Code 0.2 Hurst | Difference 0.2 Hurst |
| Matlab Code 0.4 Hurst | C SSH Code 0.4 Hurst | Difference 0.4 Hurst |
Plots at 50% depth
| Matlab Code 0.0 Hurst | C SSH Code 0.0 Hurst | Difference 0.0 Hurst |
| Matlab Code 0.2 Hurst | C SSH Code 0.2 Hurst | Difference 0.2 Hurst |
| Matlab Code 0.4 Hurst | C SSH Code 0.4 Hurst | Difference 0.4 Hurst |
Plots for bottom slice
| Matlab Code 0.0 Hurst | C SSH Code 0.0 Hurst | Difference 0.0 Hurst |
| Matlab Code 0.2 Hurst | C SSH Code 0.2 Hurst | Difference 0.2 Hurst |
| Matlab Code 0.4 Hurst | C SSH Code 0.4 Hurst | Difference 0.4 Hurst |
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.

| Matlab Code 300m L1 | C SSH Code 300m L1 | Difference 300m L1 |

| Matlab Code 300m L1 | C SSH Code 300m L1 | Difference 300m L1 |
Plots for bottom slice
| Matlab Code 100m L1 | C SSH Code 100m L1 | Difference 100m L1 |
