 +**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):
