FElupe: Finite Element Analysis

• Add optional pre-compression to shear-loadcase dof.shear(compression=0.0).
• Add MeshContainer and string-representation for Mesh objects.
• Add a mesh-reader using meshio mesh.read(filename, ...).
• Add SolidBodyNearlyIncompressible(umat, field, bulk) for (nearly) incompressible solids and a given (distortional-part only) constitutive material formulation. This is a pure displacement-based alternative to the three-field-formulation technique.

• Support an optional user-defined meshio-object in Job().evaluate(mesh=None, filename="result.xdmf").
• Support a distortional-part only Neo-Hookean material formulation with no bulk modulus defined NeoHooke(mu=1.0).

• Fix missing ArbitraryOrderLagrangeElement.points attribute.
• Fix ignored mask only_surface=True for RegionBoundary().mesh.cells_faces.
• Set default pressure to zero in SolidBodyPressure().
• Take the mesh from the global x0-field if x0 is passed to job.evaluate(x0=...).
• Fix missing update of global field x0 in job.evaluate(x0) after each completed substep.
