A namespace in which wrapper classes for PETSc objects reside.
|
inline |
Set an option in the global PETSc database. This function just wraps PetscOptionsSetValue and checks the error return value.
Definition at line 54 of file petsc_compatibility.h.
|
inline |
Set a PETSc matrix option. This function wraps MatSetOption with a version check.
Definition at line 71 of file petsc_compatibility.h.
|
inline |
Tell PETSc that we are not planning on adding new entries to the matrix. Generate errors in debug mode.
Definition at line 86 of file petsc_compatibility.h.
|
inline |
Tell PETSc to keep the SparsityPattern entries even if we delete a row with clear_rows() which calls MatZeroRows(). Otherwise one can not write into that row afterwards.
Definition at line 103 of file petsc_compatibility.h.
void PETScWrappers::petsc_increment_state_counter | ( | Vec | v | ) |
Tell PETSc that the status of the vector has changed.
Definition at line 45 of file petsc_compatibility.cc.
void PETScWrappers::petsc_increment_state_counter | ( | Mat | A | ) |
Tell PETSc that the status of the matrix has changed.
Definition at line 51 of file petsc_compatibility.cc.
PetscErrorCode PETScWrappers::pc_set_failed_reason | ( | PC | pc, |
PCFailedReason | reason ) |
Set the failed reason for the preconditioner.
Definition at line 57 of file petsc_compatibility.cc.
void PETScWrappers::snes_reset_domain_flags | ( | SNES | snes | ) |
Resets internal domain error flags in the SNES object.
Definition at line 68 of file petsc_compatibility.cc.
void PETScWrappers::snes_set_jacobian_domain_error | ( | SNES | snes | ) |
Resets internal domain error flags in the SNES object.
Definition at line 77 of file petsc_compatibility.cc.
Tell PETSc nonlinear solver to use matrix free finite differencing (MFFD).
mf_operator
indicates to use MFFD for the linear system matrix but use a user defined matrix for preconditioning purposed.
mf
indicates to use MFFD for the both the linear system matrix and the preconditioning matrix.
Definition at line 89 of file petsc_compatibility.cc.
Tell PETSc ODE solver to use matrix free finite differencing (MFFD).
mf_operator
indicates to use MFFD for the linear system matrix but use a user defined matrix for preconditioning purposed.
mf
indicates to use MFFD for the both the linear system matrix and the preconditioning matrix.
Definition at line 102 of file petsc_compatibility.cc.
void PETScWrappers::ts_reset_dm | ( | TS | ts | ) |
Reset DM (no public API).
Definition at line 132 of file petsc_compatibility.cc.
void PETScWrappers::ts_set_max_time | ( | TS | ts, |
const PetscReal | maxtime ) |
Set final time for ODE integration.
Definition at line 121 of file petsc_compatibility.cc.
void PETScWrappers::ts_set_max_steps | ( | TS | ts, |
const PetscInt | maxsteps ) |
Set maximum number of steps for ODE integration.
Definition at line 110 of file petsc_compatibility.cc.
unsigned int PETScWrappers::ts_get_step_number | ( | TS | ts | ) |
Return current step number.
Definition at line 138 of file petsc_compatibility.cc.
bool PETScWrappers::ts_has_snes | ( | TS | ts | ) |
Return true if the TS has a SNES object.
Definition at line 150 of file petsc_compatibility.cc.
|
inlinenoexcept |
Global function swap
which overloads the default implementation of the C++ standard library which uses a temporary object. The function simply exchanges the data of the two vectors.
Definition at line 869 of file petsc_vector_base.h.
