1	Modify the max number of iterations
	Allows the user to enter a maximum number of iterations to reach convergence.  For evolution problems, this maximum number holds for EACH evolution step. Default value = 10.
2	Modify the convergence test
	A relative convergence test is requested. Convergence is compared to the most pessimistic relative error with respect to all fields in the solution. Default value = 10-4
3	Modify the divergence test
	A divergence test is requested. Divergence occurs if the most pessimistic relative error is greater than a prescribed value. The divergence test saves useless iterations. However, divergence does not prevent the evolution algorithm from continuing the S-marching at a lower value of S. Default value = 10+3
