v4.0.0

New features

• Added the generation of a global spherical mesh.
• Added ridge refinement mesh2d_refine_based_on_samples.
• Added support for macOS on arm64 architecture.
• Added the calculation of curvature for curvilinear grids with curvilinear_compute_curvature.
• Added the calculation of smoothness for curvilinear grids with curvilinear_compute_smoothness.
• Gridded samples can now accept values of type numpy.int16 or numpy.float32 type for reducing memory consumption.

API changes

• Added mesh1d_add and mesh2d_add for adding meshes to existing instances.
• Added contacts_set for setting the contact indices.
• Added conversion of an unstructured mesh from spherical to Cartesian with mesh2d_convert_projection.
• Added mesh rotation with mesh2d_rotate.
• Added mesh translation with mesh2d_translate.

Other changes
