 +**Looping option, added 6th June 2013 (version 6205)**: It is possible in some cases that the nonlinear convergence tolerance can be reached before all nodes have been properly constrained.  At this point the solver can exit with some nodes retaining temperatures above the upper limit. A new option was added to check for nodes with temperatures above the limit and to continue looping if such nodes exist.  Using this option may cause more iterations but should ensure the upper limit is properly applied at all nodes.  To use it add the following line to the temperate ice solver section in the sif file (default is False):

 +Loop While Unconstrained Nodes = Logical True
