Tag also facets belonging to an outer boundary of the domain, via a callback function (that you provide) that gives the tag number for a given facet.This makes it easier to respect DRY when setting up a small problem for testing, as the internal boundaries only need to be defined in one place (in the actual geometry). Automatically tag facets on internal boundaries between two subdomains.Convenience function essentially just loops over the mesh, and packs the result into a MeshFunction.Compute the local cell volume for the whole mesh.For full examples, see _stokes and _diffusion, which use this in SUPG stabilization.

How to list the whole public API, and only the public API?.EulerianSolid and EulerianSolidAlternative.Formulation used in EulerianSolidPrimal.Formulation used in EulerianSolidAlternative.Constitutive law for linear viscoelastic materials in axial motion.Natural convection (two-way coupled problem).Forced convection (one-way coupled problem).Particularly, stabilized Navier-Stokes and advection-diffusion solvers are provided. These are mainly for use by the demos, but may be useful elsewhere. The subpackage extrafeathers.pdes contains some modular ready-made solvers. Usage examples can be found in the demo/ subfolder. Mesh import and closely related utilities run only serially. Some of our utilities do support 3D meshes, but this is currently not a priority. Each routine aims to be as general as is reasonable. The focus is on MPI-enabled 2D on P1, P2, P3, Q1, Q2, Q3, DP1, DP2, DP3, DQ1, DQ2, and DQ3 spaces. Agility and ease-of-use batteries for the Python layer of the FEniCS finite element framework.
