To turn off output for a given output manager (look a the JSON file as 
Charles suggested and/or look at the VTK files to see what information 
they contain (fault, state variables, solution field, etc), simply set 
the vertex_data_fields and/or cell_data_fields to empty arrays:

vertex_data_fields = []
cell_data_fields = []

Brad
