v3.0.1

What's Changed

Minor patch that fixes the nuspec package input configurations. Otherwise identical to v3.0.0.

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.
• Performance has been enhanced by utilizing 32-bit integers for unsigned indexes.
• The refinement of a polygon perimeter has been improved.
• The polygon class has been refactored.
• The generation of curvilinear grids has been improved by introducing Eigen.
• Input and parameter range checks are now in place. When invalid values are specified, exceptions are thrown and errors are registered.

API changes

• Improve performance of search algorithms mkernel_mesh2d_get_edge and mkernel_mesh2d_get_node_index by introducing a bounding box defining the search area.
• Small, non-contiguous regions of an unstructured mesh can be removed using the mkernel_mesh2d_remove_disconnected_regions function.
• Quadrangular unstructured meshes can now be connected using the mkernel_mesh2d_connect_meshes API function.
• Snapping a polygon to a land boundary is now possible with the mkernel_polygon_snap_to_landboundary function.
• Snapping a spline to a land boundary is now available through the mkernel_splines_snap_to_landboundary function.
• mkernel_curvilinear_make_uniform is now divided in 3 apis for separating responsibilities
  • mkernel_curvilinear_make_rectangular_mesh: for making a curvilinear mesh based on origin, rows and columns
  • mkernel_curvilinear_make_rectangular_mesh_from_polygon: for making an curvilinear mesh inside a polygon with defined block sizes
  • mkernel_curvilinear_make_rectangular_mesh_on_extension: for making an curvilinear mesh on a defined area using defined block sizes
• mkernel_mesh2d_make_uniform is now divided in 3 apis for separating responsibilities
  • mkernel_mesh2d_make_rectangular_mesh: for making an unstructured mesh based on origin, rows and columns
  • mkernel_mesh2d_make_rectangular_mesh_from_polygon: for making an unstructured mesh inside a polygon with defined block sizes
  • mkernel_mesh2d_make_rectangular_mesh_on_extension: for making an unstructured mesh on a defined area using defined block sizes
• Triangular mesh generation functions have been renamed as follows:
  • mkernel_mesh2d_make_mesh_from_polygon -> mkernel_mesh2d_make_triangular_mesh_from_polygon
  • mkernel_mesh2d_make_mesh_from_samples -> mkernel_mesh2d_make_triangular_mesh_from_samples
• The mkernel_mesh2d_delete function now supports only two options: InsideNotIntersected = 0 and InsideAndIntersected = 1. This algorithm supersedes the previous mesh deletion algorithms.
• edge_faces and face_edge have been added to the meshkernelapi::Mesh2D structure to allow the reconstruction of the faces

Bug fixes

• Account for boundary edges in mkernel_mesh2d_get_orthogonality, mkernel_mesh2d_get_smoothness
• The translation of large polygons in spherical coordinate generates erroneous results when used to inquire if a point is in polygon

v2.0.0

What's Changed

API changes

• Added mesh refinement based on bilinear interpolation: mkernel_mesh2d_refine_based_on_gridded_samples
• Added a projection factor in mkernel_contacts_compute_single, for generating 1D2D contacts when 1D nodes are not inside the mesh2d
