Has new AMG parameters set was preconditioner #69
Copied square3 to square4, which does parallel outflow. Now changing to
tangential flow
Changed GMRES tolerance and Newton solve tolerance to 1.0e-6 from 1.0e-8
Tangential flow working. GMRES and Newton solver tolerance is changed
from 1.0e-8 to 1.0e-6
Copied sq4 to sq5, about to do double outflow
sq3 is working Po, sq4 is wokring Tf, Sq5 is working PoTf
Starting quater circle 2D
Added additional files to track
Renamed some datafiles...
