Updates the requirements on Gridap to permit the latest version.

Release notes

Sourced from Gridap's releases.

v0.20.10

Gridap v0.20.10

Diff since v0.20.9

This release adds many new ReferenceFEs, within the moment-based framework recently introduced in 0.20. In particular,

• Argyris and Morley
• HHJ, Regge and GLS
• Tai-Winther (conforming and nonconforming)
• MTW

We also add a new general framework CartProdRefFE to allow users to build cartesian products of ReferenceFEs. This allows, for instance, a (Lagrange, Lagrange, Argyris) vector-valued element for Reissner–Mindlin plate bending equations.

Finally, we introduce two completely novel bases on tetrahedra, BarycentricPΛBasis and BarycentricPmΛBasis that unlock efficient and numerically stable HCurl-conforming spaces on meshes with non-oriented faces.

[0.20.10] - 2026-09-22

Added

• Since PR#1335.
  • New variants (accessible via kwarg flavor=:BMM) of the BarycentricPΛBasis and BarycentricPmΛBasis bases of the PᵣrΛᵏ and P⁻ᵣrΛᵏ spaces. For form order k=1, both flavors of both bases implement a closed-form change-of-basis with respect to relabelling/permutation of the simplex vertices.
  • Added the associated reference FEs (named rotating_pλ, trimmed_pλ) which provide H(curl)-conforming FE spaces on meshes with arbitrary simplex ordering (NonOriented).
  • Initial experimental support (API is still unstable) for tensor calculus and Finite Element Exterior Calulus (FEEC): added ExteriorFormValue, a MultiValue representing alternating K-forms, with pointwise exterior calculus (wedge, interior product, Hodge star, musical isomorphisms, Koszul operator, pullback/pushforward), and lazy Field counterparts for some of them.
  • New experimental extension for Symbolic.jl (API is still unstable): it provides support of symbolic exterior calculus (exterior derivative, codifferential, Lie derivative).
• Since PR#1336, new ReferenceFEs added to the library:
  • Added ArgyrisRefFE, the quintic C¹-conforming Argyris triangle. It comes with the new H2Conformity, which can be explicitly requested by passing any of :C1, :H2, :Hhess, :HHess.
  • Added MorleyRefFE, the quadratic nonconforming Morley triangle.
  • Added HHJRefFE, ReggeRefFE and GLSRefFE: the Hellan-Herrmann-Johnson, Regge and Gopalakrishnan-Lederer-Schoberl (second kind) triangles, of any degree r >= 0, normal-normal, tangential-tangential and normal-tangential continuous respectively.
  • Added DubinerBasis, the L2-orthonormal (Dubiner/Koornwinder) polynomial basis of P_K on the reference simplex in any dimension.
  • Added ArnoldWintherNCRefFE and ArnoldWintherCRefFE, the nonconforming (15 DoFs, P2-based) and conforming (24 DoFs, P3-based) Arnold-Winther symmetric stress triangles for mixed elasticity. Both are built as constrained subspaces of a larger prebasis, so length(get_prebasis(reffe)) > num_dofs(reffe) for them.
  • Added MardalTaiWintherRefFE, the Mardal-Tai-Winther element on triangles (9 DoFs) and tetrahedra (24 DoFs).
  • Added the missing product_rule methods for ⋅ and outer.
  • Added CartProdRefFE, the Cartesian product of reference elements sharing a polytope and a value type, stacked along a new last index: Float64 becomes VectorValue{K} and VectorValue{d} becomes TensorValue{d,K}.

Fixed

• Fixed refine dropping the map and isperiodic fields of the CartesianDescriptor when refining a CartesianDiscreteModel. Since PR#1334.

[0.20.9] - 2026-08-17

Added

• Better control of num_nearest_vertices for KDTreeSearch. Added a new preference set_num_nearest_vertices to set a global default for the library. Since PR#1312.
• Add AD support for complex-valued DOFs. Since PR#1325.
• Added Base.adjoint method for ArrayBlock. Since PR#1325.

Fixed

• Fixed the dof signs flips for Curl-conforming reference FE bases for elements with change_dof=true. The signs are now tested for consistency with the change_dof=false version. Since PR #1315.
• Fixed evaluation of weak forms on empty trians with inverse maps. Since PR#1316.
• Fixed getting field type when changing domain on empty adapted triangulations. Since PR #1326.
• Fixed broadcasting of operation on TensorValue{A,B} components, and added broadcasting to Third/HighOrderTensorValue. Since PR #1331.

Changed

• Changed product_rule to allow for numbers of Complex type. Since PR#1325.
• Simplified the type parameters of BernsteinBasisOnSimplex and BarycentricP(m)ΛBasisChanged. The change of coordinate matrix is always stored, with Float64 precision. Since PR#1330.

[0.20.8] - 2026-06-01

Added

• Added type-stable methods to tensor_contraction and Base.permutedims(::MultiValue, perm): pass the arguments by Val. Since PR#1301.
• Added compose_glues and compress_adaptivity, which are tools that can be used to compress a mesh hierarchy (several levels of refinement) into a single adapted model. Since PR#1309.

Fixed

Blocking to avoid accidental merge.
Before upgrading, TensorAlgebra needs refactor to support multi-dimensional indexing for high order tensor values.
