7: PetscBag - PETSc object that manages a collection of user data including parameters.
8: A bag is essentially a C struct with serialization (you can save it and load it from files).
10: Level: beginner
12: Sample Usage:
13: $ typedef struct {
14: $ PetscInt height;
15: $ PetscScalar root;
16: $ PetscReal byebye;
17: $ } MyParameters;
18: $
19: $ PetscBag bag;
20: $ MyParameters *params;
21: $
22: $ PetscBagCreate(PETSC_COMM_WORLD,sizeof(MyParameters),&bag);
23: $ PetscBagGetData(bag,(void **)¶ms);
24: $ PetscBagSetName(bag,"MyParameters");
25: $ PetscBagRegisterInt(bag,¶ms.height,22,"height","Height of the water tower");
