Isn't this redundant? 104: PetscBagRegisterReal(bag, &user->alpha, 1.0, "alpha", "Linear coefficient"); 105: PetscBagRegisterReal(bag, &user->lambda, 6.0, "lambda", "Nonlinear coefficient"); 106: PetscBagSetFromOptions(bag); 107: PetscOptionsGetReal(PETSC_NULL,"-alpha",&user->alpha,PETSC_NULL); 108: PetscOptionsGetReal(PETSC_NULL,"-lambda",&user->lambda,PETSC_NULL); (from http://www.mcs.anl.gov/petsc/petsc-current/src/snes/examples/tutorials/ex8.c.html )
Doesn't the PetscBagSetFromOptions allow you to load values into the structure using "-name", which means that the capabilities in lines 107 and 108 are implicit in the "PetscBagSetFromOptions" call. Or do I not understand what PetscBagSetFromOptions does? -Andrew -------------- next part -------------- An HTML attachment was scrubbed...
