I think calling CVODE from threads causes memory leaks. A somewhat minimal reproducer is given by the following code sample: ```julia using ModelingToolkit, OrdinaryDiffEq, Sundials, Evolutionary function objective(p, solver=CVODE_BDF()) @parameters...

Currently the binary operator $\cdot$ gets automatically replaced with a normal $*$ when constructing symbolic representations. MWE: ```julia julia> @variables x y; julia> using Tensors julia> x ⋅ y x*y...

This PR shows how to implement matrix-free operators on the GPU and provides the necessary infrastructure. ## TODOs * [x] Fix bug when block size > 1 * [x] Use...

Users often seem to want to have the ability that the node numbering and dof numbering coincides. We might want to consider providing a helper routine for this. Prototype: ```julia...

This needs quite a bit of polishing, but it is at least a functional example. ![reactive-surface](https://github.com/Ferrite-FEM/Ferrite.jl/assets/9196588/a2975c20-36c0-4a6b-979d-a4a0553223ec) ## TODO * [ ] ~~Parameter passing for diffusivity~~ * [x] Documentation * [...

It might be a fun project to implement a frontal solver to see where we are to develop specialized linear solvers. A starter should be the original paper by Irons...

Point evaluation on master just does not work on nonlinear geometries. Here is an attempt to make it work. Fixes https://github.com/Ferrite-FEM/Ferrite.jl/issues/763 but might not completely fix the point eval. ##...
