TSCreate#
This function creates an empty timestepper. The problem type can then be set with TSSetProblemType() and the type of solver can then be set with TSSetType().
Synopsis#
#include "petscts.h"
PetscErrorCode TSCreate(MPI_Comm comm, TS *ts)
Collective
Input Parameter#
comm - The communicator
Output Parameter#
ts - The
TS
Developer Notes#
TS essentially always creates a SNES object even though explicit methods do not use it. This is
unfortunate and should be fixed at some point. The flag snes->usessnes indicates if the
particular method does use SNES and regulates if the information about the SNES is printed
in TSView(). TSSetFromOptions() does call SNESSetFromOptions() which can lead to users being confused
by help messages about meaningless SNES options.
