3D and 2D geomechanical restorations may be performed in ParaGeo. The main data structures used to perform ParaGeo restorations are:

 

•Restoration_data defining the conditions for the restoration stage such as the restoration operation to be performed (e.g. translation of top surface, deactivation of top stratigraphy unit, etc), decompaction conditions, assumptions for the top surface, etc.

 

•Part geometry data (Part_geometry_set, Part_nodal_data, Part_line and Part_surface) to define the restoration datum (restoration surface).

 

 

In the present reference manual pages an overview of restoration in ParaGeo and description of Restoration_data data structure and available keywords is provided.

 

Note that ParaGeo has the capability to generate a forward analysis derived from restoration output results. For example the final restored geometry will be the initial geometry for the forward model and the kinematics at restoration model boundaries can be reversed to generate boundary conditions for the forward model.  To this end a restoration to forward conversion datafile usually needs to be defined with the relevant data structures and keywords described in Restoration to Forward pages.
