#include "petscdm.h" #include "petscdmlabel.h" #include "petscds.h" PetscErrorCode DMComputeError(DM dm, Vec sol, PetscReal errors[], Vec *errorVec)Collective on DM
dm | - The DM | |
sol | - The solution vector | |
errors | - An array of length Nf, the number of fields, or NULL for no output | |
errorVec | - A Vec pointer, or NULL for no output |
errors | - The error in each field | |
errorVec | - Creates a vector to hold the cellwise error |
Note: The exact solutions come from the PetscDS object, and the time comes from DMGetOutputSequenceNumber().
