GSS2022 - Day 2 - Gridding and Radiation - May 17

•  Gmsh
• ex00 is the very first tutorial on how to create a mesh for simple domain. The aim are to understand what are the geometrical entities, point, line, curve loop, and plane surface, required to define the computational domain (pdf, tutorial, Vimeo, Vimeo practice);
• ex01 shows how to control the mesh refinement (pdf, tutorial, Vimeo, Vimeo practice);
• ex02 deals with the creation of subdomains. Subdomains allows the user to assign different sets of parameters to mesh elements, and thinking about solving  the Richards' equation means to include a specific soil stratigraphy  (pdf, tutorial, Vimeo, Vimeo practice);
• ex03 addresses the problem of specifying different boundary conditions (pdf, tutorial, Vimeo, Vimeo practice).

    Here you can find the examples as those presented in the .pdf. We thank Enrico Borinato for his help         in preparing the material for the Gmsh tutorials.
