Program crashes when threshold value goes over 1.

[xMestas]

The maximum DIC is 1. If the threshold value goes over 1, all species will be removed. The program will then crash when trying to determine the auto ignition delay of the reduced model. This can occur if the maximum allowed error value is too high.

This can be fixed by causing the program to stop incrementing the threshold value once it reaches 1.

This issue can be replicated with the following test case:

Model: Artificial_Mech.cti
Initial Conditions:
Pressure :: 1 atm
Equivalence ratio :: 1.0, Fuel of H, oxidizer of O2.
Temperature :: 500 Kelvin
Error allowed: 5%
Method: DRG
Targets: H
Retained Species: H, O2
