3D elasticity complex with mixed elements with weak symmetry enforcement (only "primal" method, based on only displacement dofs, is demonstrated in Freefem documentation) **Describe the solution you'd like** Would like...
Add trimmed serendipity Backport from firedrake/fiat/trimmed serendipity branch (Needs corresponding ufl and ffc changes as well) Hmm. I think this requires more extensive changes. Update: Primary problem appears in fiatinterface.py...
### Describe the bug @robimarko When I use the Fritz repeater 1200 (IPQ40xx/AR8035) to route my internet through vlan, performance is very low (200 Mbit/s) (router on a stick) core...
This commit generates the proper orthonormal rational functions for the pyramid. See https://github.com/FEniCS/basix/issues/894 Still doing more checks on the derivatives, especially around p=q. The Lagrangian elements have a problem with...
Currently, the base functions for pyramids are regular polynomials: https://docs.fenicsproject.org/basix/main/cpp/namespacebasix_1_1polyset.html However, they need to be rational polynomials: https://defelement.org/elements/examples/pyramid-lagrange-equispaced-2.html https://www.math.u-bordeaux.fr/~durufle/montjoie/pyramid.php The following relative minor changes should be performed: min(p,q) should be...
Attempting to make a generic conformal DeRham element here. Element: Scope: line, triangle, quadrilateral, tetrahedron, pyramid, prism, hexahedron Full spaces (P) or trimmed spaces (P-) Serendipity or tensor product Tensor...
Refer to: https://github.com/TESSEorg/ttg/issues/86 https://github.com/FEniCS/dolfinx/pull/3734 to build on current debian testing (trixie), which is on adios2 2.10.2
@mscroggs According to https://github.com/mscroggs/symfem/blob/main/symfem/elements/tnt.py, we need to multiply by the primary bubble function, and take the Laplacian for the interior dofs. To this end tabulation which also generates the derivatives...
Symmetric pyramid for Cockburn & Fu functions Even though Cockburn and Fu https://arxiv.org/pdf/1605.00132 use asymmetric pyramids, the proposed functions are not easily orthogonal. Furthermore, we need the derivatives of the...
