The gamma value of the OJL model had been limited to values above 150 1/cm to avoid numerical problems. This restriction has been removed in the following way: As a new available option you can set the limit yourself, executing the menu command File/Options/Optical model/Set minimum value of gamma in OJL models. The new limit is applied to all OJL models that you use in this particular configuration. Note, however, that the new value is not stored as a general setting – it is only active and stored in the configuration you are working with.
