PetscBag

 PETSc object that manages a collection of user data including parameters. A bag is essentially a C struct with serialization (you can save it and load it from files).

Synopsis

typedef struct _n_PetscBag*     PetscBag;

Sample Usage

     typedef struct {

        PetscInt     height;

        PetscScalar  root;

        PetscReal    byebye;

     } MyParameters;



     PetscBag     bag;



     MyParameters *params;





     ierr = PetscBagCreate(PETSC_COMM_WORLD,sizeof(MyParameters),&bag);



     ierr = PetscBagGetData(bag,(void **)&params);



     ierr = PetscBagSetName(bag,"MyParameters");



     ierr = PetscBagRegisterInt(bag,&params.height,22,"height","Height of the water tower");
