v3.0.0

Major improvements

• A new efficient mesh deletion algorithm has been introduced, allowing for the deletion of a mesh based on a polygon with two options:
  • Delete faces inside the polygon that are not intersected by the polygon segments.
  • Delete faces inside the polygon that are intersected by the polygon segments.
• Minimum edge size in meters is now taken into account when refining a mesh based on a polygon or samples, both in spherical and Cartesian coordinates.
• Mesh refinement based on the Courant criteria now considers the max_courant_time.
• Improved the generation of rotated curvilinear grids within a polygon.
• The refinement of a polygon perimeter has been improved.
• The size of the internal arrays in GeometryList is now checked

API changes

• The MeshKernel class instance now accepts a ProjectionType enumeration as a constructor parameter, replacing the previous boolean parameter.
• Strong typing is now mandatory for all parameters used in the MeshKernel API.
• Improved the performance of search algorithms mesh2d_get_edge and mesh2d_get_node_index by introducing a bounding box defining the search area
• GeometryList is now optional in contacts_compute_boundary
• Small, non-contiguous regions of an unstructured mesh can be removed using the mesh2d_remove_disconnected_regions function.
• mesh2d_make_uniform is now divided in 3 apis for separating responsabilities
  • mesh2d_make_rectangular_mesh: for making an unstructured mesh based on origin, rows and columns
  • mesh2d_make_rectangular_mesh_from_polygon: for making an unstructured mesh inside a polygon with defined block sizes
  • mesh2d_make_rectangular_mesh_on_extension: for making an unstructured mesh on a defined area using defined block sizes
• Triangular mesh generation methods have been renamed as follows:
  • mesh2d_make_mesh_from_polygon -> mesh2d_make_triangular_mesh_from_polygon
  • mesh2d_make_mesh_from_samples -> mesh2d_make_triangular_mesh_from_samples
• Quadrangular unstructured meshes can now be connected using the mesh2d_connect_meshes API function.
• The mesh2d_delete function now supports only two options: INSIDE_NOT_INTERSECTED = 0 and INSIDE_AND_INTERSECTED = 1. This algorithm supersedes the previous mesh deletion algorithms.
• edge_faces and face_edges have been added to Mesh2D structure to allow the reconstruction of the faces.

Bug fixes

• Corrected the computation of the number of interpolation locations in mesh2d_averaging_interpolation and mesh2d_triangulation_interpolation
