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.
