 Hi

 I am going to implement cell center difference method for
 u = - K grad p
 div u = f
 where p is the pressure , u is the velocity, f is the source term.

 my goal is to assemble the matrix and test the performance of different 
 linear solvers in parallel.

 my question is how can I read the input file for K where K is n*n 
 tensor.

 second one is that do you have any similar examples?
