Bugfix for periodic NURBS meshes in parallel [periodic-nurbs-dev]

13

This PR fixes a bug that precluded running periodic BCs in parallel. It also fixes some issues when specifying the periodicity in the mesh file instead of a separate file....

Adding H(div) and H(curl) conforming NURBS FiniteElements

11

This PR adds H(div) and H(curl) conforming NURBS FiniteElements. The functionality is tested in the _miniapps/nurbs_ where several apps are added. This PR also adds the option to project a...

New ode solver selection mechanism[ab-am-refactor]

25

This PR does some small refactoring on the ODE solver class. 1) It provides a selection mechanism for ODE solvers, which cna be used in examples and miniapps. This avoids...

Small type fix in `dgmass`. | PR | Author | Editor | Reviewers | Assignment | Approval | Merge| | --- | --- | --- | --- | --- |...

Request for input: Laplace-based linear and bilinear integrators

29

I am interested in implementing `LinearFormIntegrator` and `BilinearFormIntegrator` involving the Laplacian. Any heads up on potential conflicting or duplicate effort is highly appreciated. Any tips or warning for pitfalls are...

Autodiff function for coefficient [add-ad-coeff]

1

This PR defines as helper class that can convert user provided functions in to first order derivatives, that can be used by the various `XXXFunctionCoefficient` classes. The functions need to...

This PR is a small rewrite of example 23, the essential BC are handled in a slightly cleaner way. This also corrects the issue mentioned in issue #4181.

Nodal interpolation for NURBS

51

Changed PR header (27 June 2024) This PR adds a Projector to the NURBS-based elements. Furthermore, initialization of the a NURBS-based` FESpace` made to look similar to the initialization of...

Add gradients to Vector FE

1

This PR requires #4326 This PR adds Gradients to vector-valued finite elements. This allows H(div) elements to be used to solve a Stokes problem, for instance. Only NURBS-based vector-valued finite...
