v7.7.0

[7.7.0] - 2023-08-31

Added

• Add optional normalization of mesh runouts (which are then indents) by mesh.runouts(normalize=False).
• Add LinearElasticLargeStrain(E=None, nu=None, parallel=False), suitable for large-rotation analyses. This is based on NeoHooke() with converted Lamé-constants.
• Add a simple boundary-based quad- or hex mesher: A mesh tool for filling the face or volume between two line- or quad-meshes mesh.fill_between(mesh, other_mesh, n=11).
• Add Circle(radius, centerpoint, n) for the creation of a quad-meshed circle.

Changed

• Update the mesh also with a new points array: this changes the Mesh-update function mesh.update(cells, cell_type=None) to mesh.update(points=None, cells=None, cell_type=None). Note that this could break old scripts which use mesh.update(new_cells) instead of mesh.update(cells=new_cells).
• Move the copy-method of a Mesh Mesh.copy() to its base-class and extend it to optionally update the attributes DiscreteGeometry.copy(points=None, cells=None, cell_type=None).

Removed

• Remove tests on Python 3.7 (end of life).
