API Reference

The core functionality of GmshModel is the mesh generation for complex models using Gmsh and the Gmsh-Python-API. The creation of such complex models, often requires methods for the geometry generation. To this end, basic geometric objects and helper methods for, e.g., distance calculations are provided within the Geometry module of GmshModel: using boolean operations for groups of basic geometric objects, complex models can be defined step by step. An extension of the modules will help to broaden the range of available models.

After the geometry is defined, it has to be transferred into a Gmsh model: all geometric objects are translated to their Gmsh representations, boolean operations are performed and physical groups are added to the model. Within the Model module of Model, predefined models can be found. Since, so far, the focus of GmshModel was on mesh models for representative volume elements with multiple, randomly placed inclusions, especially those models are already defined in GmshModel. However, since the GenericModel defines all required methods for the model generation, the basic tasks for the development of a new model are the definitions of required geometric objects and their arrangement within the model, of boolean operations and physical groups to be performed/added in Gmsh and of refinement information for an auomated mesh size computation.

Finally, basic GUIs for the geometry and mesh visualization are defined within the Visualization module.
