The ''Options'' tab includes general SUB package options, options for saving and restarting Dstart and DHC values for delay interbeds, and material values for delay interbeds. The options are as follows: | The ''Options'' tab includes general SUB package options, options for saving and restarting Dstart and DHC values for delay interbeds, and material values for delay interbeds. The options are as follows: | ||
*'''NN''' – Number of nodes used to discretize the half space to approximate the head distributions in systems of delay interbeds. | *'''Comments''' – Place whatever comments are needed for the package. | ||
*'''NN''' – Number of nodes used to discretize the half space to approximate the head distributions in systems of delay interbeds. Defaults to zero when there aren't any delay interbed layers specified. | |||
*'''AC1''' – Is an acceleration parameter. Used to predict the aquifer head at the interbed boundaries on the basis of the head change computed for the previous iteration. Values may range from 0.0 to 0.6. | *'''AC1''' – Is an acceleration parameter.

*'''ITMIN''' – The minimum number of iterations for which one-dimensional equations will be solved for flow in interbeds when the [[GMS:SIP_Package|SIP package]] is used. | *'''ITMIN''' – The minimum number of iterations for which one-dimensional equations will be solved for flow in interbeds when the [[GMS:SIP_Package|SIP package]] is used. | ||
*'''SUB Output Options''' – Brings up a dialog where SUB package output options can be set. Values can either be printed to the model output file or saved as a binary file. The Save vert. disp. (Ifl8) option saves a binary file for vertical displacement that is included in the model solution as a dataset. | *'''SUB Output Options''' – Brings up a dialog where SUB package output options can be set.
