Model 5 - Fault

This script demonstrates how to create a simple fault model with constant offset using GemPy, a Python-based, open-source library for implicit geological modeling.

Plot the initial geological model in the y direction

gpv.plot_2d(geo_data, direction=['y'], show_results=False)

# Plot the result of the model in the x and y direction with data
gpv.plot_2d(geo_data, direction='y', show_data=True)
gpv.plot_2d(geo_data, direction='x', show_data=True)

gpv.plot_3d(geo_data, show_data=True, show_boundaries=True, show_lith=True)
