This example is extended from the 2D model, which is detailed in Rest_002. In the following demonstration, discussions about boundary conditions, sedimentation horizons and fault propagation pathways are not repeated since the ideas are analogous to the 2D counterpart.

 

In the current work flow, users are provided with some flexibility to import geometry models from other sources, instead of applying the standard ParaGeo procedure (i.e. defining geometry through Nodal_data, Geometry_line, Geometry_surface and Geometry_volume).

 

In this example, a present-day 3D model with normal fault is created and meshed in Gmsh. In particular, the 2D plane model is extruded with a thickness of 500m. After conversion (discussed in Gmsh_tutorial_example), the geometry definition then becomes compatible and is fully recognised by ParaGeo.

By the end of this tutorial, the user should be more familiar with

1.ParaGeo data file setup corresponding to geomechanical restoration in 3D;

2.Generation of data file for forward analysis using restored model;

3.Fault insertion onto newly deposited layer(s) during forward simulation.
