program main_aggr

(

)

Main program for running DOUG with input files in assembled form.

Running the aggregation-based DOUG code: (example)

mpirun -np 3 doug_aggr -f doug.ctl where doug.ctl may contain the following fields

Input-file example:

 solver 2
 solve_maxiters 300
 method 1
 fine_method 1
 coarse_method 1
 levels  2
 overlap -1
 smoothers 0
 num_iters 4 # Gauss-Seidel iterations
 grid_size 100 # Structured grid size
 input_type 2
 symmstruct T
 symmnumeric T
