FElupe: Finite Element Analysis

• Add a new argument to pass a mesh for the dual regions in FieldsMixed(mesh=None).
• Add quadrature and grad arguments to RegionLagrange.
• Add order attribute to RegionLagrange.
• Add items-argument for custom slicing of characteristic curve plots in CharacteristicCurve.plot(items=None).

• Enhance Domain integration in IntegralForm: Ensure C-contiguous arrays as fun-argument.
• Enhance performance of hyperelastic material model formulations using automatic differentiation.
• Perform reshape and broadcasting if user-defined Field-values with correct size are given.
• Make symmetry-related boundary conditions in uniaxial loadcase optional dof.uniaxial(sym=True).
• Merge custom point- and cell-data dicts with default dicts in Job instead of replacing them, also add Job(point_data_default=True, cell_data_default=True).
• Allow to change cell-type in Mesh.update(cells, cell_type=None).
• Enhance the creation of a disconnected mesh for mixed-field formulations by Mesh.disconnect(points_per_cell=None, calc_points=True).
• Change required to optional arguments in Step(items, ramp=None, boundaries=None).

• Fix broadcast arrays for the geometric stiffness contribution of hyperelastic material model formulations using automatic differentiation.
