Todo list for DGMulti solvers
This is intended to track additional tasks for solvers on simplicial (and more general) meshes
- [x] consider the use of
matmul!
from Octavian.jl - are we OK with adding this as an additional dependency? - [x] Add Plots to
test/Project.toml
and enable all tests once upstream issues are fixed - [x] switch to dispatch instead of using
UniformScaling
interpolation/projection matrices for nodal SBP methods https://github.com/trixi-framework/Trixi.jl/pull/647#discussion_r661498313 - [x] Add solver for tetrahedral meshes (now supported in StartUpDG!)
- [x] add flux differencing for modal and SBP triangular DG
- [x] add flux differencing for modal tetrahedral DG
- [x] add sparsity-optimized flux differencing for tensor product DG (see https://github.com/trixi-framework/Trixi.jl/pull/757)
- [x] add visualization for
DGMulti
(see https://github.com/trixi-framework/Trixi.jl/pull/755)
Solvers:
- [x] specialize volume integral on non-affine/curved meshes (do not use split forms by default)
- [x] add GSBP solver type for Gauss nodes (#781, https://github.com/trixi-framework/Trixi.jl/pull/927)
- [x] optimize GSBP solver using sparse
mul!
(see https://github.com/trixi-framework/Trixi.jl/pull/927#issuecomment-954308546) or tensor product operations for face interpolation - [x] decide whether we want to implement generalized SBP solvers on simplices (no for now, it is probably not much more efficient than
Polynomial()
solvers) - [x] use WADG (generalized mass lumping) for
invert_jacobian
on appropriate meshes. - [ ] Add 3D tetrahedral SBP operators (needs upstream changes in StartUpDG)
Analysis
- [x] normalize L2 errors in analysis (https://github.com/trixi-framework/Trixi.jl/issues/862)
Meshes:
- [ ] convert between
UnstructuredQuadMesh
andAbstractMeshData
types for use with quad/hex solvers. - [ ] Convert between
CurvedMesh
andAbstractMeshData
for uniform meshes - [x] #961
- [x] Mark
VertexMappedMesh
for deprecation, replace with something more descriptive (e.g.,MeshDataMesh
orDGMultiMesh
)
Nonconservative terms:
- [x] Added for
approximation_type = Polynomial()
- [x] Added for
approximation_type = SBP()
- [x] Add new capabilities to the overview in the docs
Feature requests/suggestions welcome!
Octavian.jl - are we OK with adding this as an additional dependency?
Yes - it's already an indirect dependency via StrideArrays.jl
I added
Add StartUpDG.jl as direct dependency instead of using it via Requires.jl?
to the list above
Added
specialize
Semidiscretization
to allowDGSEM
to work withVertexMappedMeshes
Adding
add visualization for
DGMulti
