v4.0.0

Changelog since [3.1.0] - 2022-05-02

Added

• Add SolidBody.evaluate.kirchhoff_stress() method. Contrary to the Cauchy stress method, this gives correct results in incompressible plane stress.
• Add SolidBodyTensor for tensor-based material definitions with state variables.
• Add bodies argument to newtonrhapson().
• Add a container class for fields, FieldContainer (renamed from FieldMixed).
• Add len(field) method for FieldContainer (length = number of fields).

Changed

• Unify handling of Field and FieldMixed.
• Constitutive models use lists as in- and output (consistency between single- and mixed-formulations).
• Allow field updates directly from 1d sparse-solved vector without splitted by field-offsets.

Fixed

• Fix tovoigt() helper for data with more or less than two trailing axes and 2D tensors.
• Fix errors for force() and moment() helpers if the residuals are sparse.

Removed

• Remove wrapper for matADi-materials (not necessary with field containers).
• Remove IntegralFormMixed and IntegralFormAxisymmetric from global namespace.
