2a8381b23c702518c6b1ccbeafee50b9375df0e4 - Add automatic generated fortran support for setting and returning contexts

Tue, 13 Jan 2026 04:45:38 +0000

Add automatic generated fortran support for setting and returning contextsMajor cleanup of the code for setting and returning application (previously called user) contexts - PetscCtx ctx is now the standard for passing in contexts - PetscCtxRt ctx is the standard for passing out contexts, including context destroy routines based on PetscCtxDestroyFnBoth of these are typedef to void*Also removed most use of user and userctx for context arguments now consistently named ctxImproved documentation on PetscCtx and PetscCtxRt and on how to use contexts (including getting them) from Fortran List of files: /petsc/include/petscsnes.h

Improve the propagation of function domain error handling in SNES, especially in the line search routines.Due to the object layering of SNESLineSearch under SNES there is some code duplication include both SNESLineSearchReason and SNESConvergedReason and SNESCheckFunctionNorm() and SNESLineSearchCheckFunctionNorm() and Jacobian friendsReported-by: david.knezevic@akselos.com List of files: /petsc/include/petscsnes.h

SNESLinesearch: Minor improvements- add missing configuration options in the documentation of the line searches (some of the available options were not listed), and consistently list their respective default values- add proper convergence criteria for the secant method in the L2 line search based on ltol and atol (otherwise, the secant method is mostly running for the maximum number of iterations)- fix a small bug in the CP line search, where steptol * lambda was used to check for convergence based on the change of lambda instead of the ltol parameter- rename sneslinesearch->maxstep to sneslinesearch->maxlambda in the options database to be consistent with its purpose in the algorithms- rename SNESLineSearchL2 to SNESLineSearchSecant to better represent its underlying approach List of files: /petsc/include/petscsnes.h

Thu, 20 Feb 2025 06:12:11 +0000

Fortran 90: fully embrace After 34 years!- deprecate use of 'F90' in Fortran function names- use Fortran pointers when appropriate- the new Fortran API is not backward compatible with previous versions!- also clean up inconsistent PETSc code detected by new Fortran generation tools- drop use of bfort- automatically generate all the Fortran PETSc objects, enums etc from the include files- generate most of the Fortran interface definitions and functions from the source code- simplify the number and organization of Fortran modulesCo-authored-by: Jose E.

Mon, 17 Feb 2025 19:49:49 +0000

SNESLineSearch: fix computation of directional derivative in the case of the VI solversThe two line search algorithms bisection and critical point work with the directional derivative, assuming that F(x) = grad G(x).However, when working with the variational inequality solvers, the constraints were not correctly considered when computing the directional derivative.This commit introduces a new linesearch->ops->vidirderiv function which correctly considers the constraints (similar to linesearch->ops->viproject and linesearch->ops->vinorm).
