[Libmesh-users] MatSetBlockSize

[Ataollah M. <am...@ti...>]

Dear all,

I was wondering if someone can tell me if I can set the block size for a linear system's matrix?

If yes where (at what point )?

 I'm thinking of doing something like: 

PetscMatrix<Number>* matrix = libmesh_cast_ptr<PetscMatrix<Number>*>(system.matrix);
MatSetBlockSize(matrix->mat(), dim);

Thanks,
Ata
