Yeah, we'd like the implementation to stay in alpha2.c. There could be a new
interface TSAlpha2SetPredictorType (with -ts_alpha2_predictor_type
[none,same_velocity,...]) or TSAlpha2SetPredictorFunction.

Hi Jed,
The current workaround I'm using is very minimal and basically just moves
the definition of `TS_Alpha` from `alpha2.c` up to `petsc/private/tsimpl.h`
(and renames it to avoid a conflict with `TS_Alpha` in `alpha1.c`), but I
gather that we're really still not "supposed to" include that

Some other TS implementations have a concept of extrapolation as an initial
guess. Such method-specific initial guesses sound like they fit that pattern
and would be welcome to be included in alpha2.c. Would you be willing to make a
merge request to bring your work upstream?

Hi,
I'm currently working with 3D DMPlex and performing crucial calculations
involving face normals and edge tangents. I've noticed that face normals are
directed from support[0] to support[1]. However, I'm uncertain about the
conventions for edges and vertices in relation to faces.
Hi Jed,
What I'm trying to compute is basically a standard same-velocity or
same-acceleration predictor (although slightly more complicated, since I'm
restricting it to a sub-system). I hadn't looked into
`SNESSetComputeInitialGuess` yet, although one difficulty is that it would
need access to
Good Morning Prof. Knepley,
Thank you for the update. I am now able to run the code. However, it does not
appear to solve the problem correctly. The only results available are the
initial conditions (temp = 100). In the problem, one face is set to 1400 and
another face is set to 100. Since the
I think you can use TSGetSNES() and SNESSetComputeInitialGuess() to modify the
initial guess for SNES. Would that serve your needs? Is there anything else you
can say about how you'd like to compute this initial guess? Is there a paper or
something?
