If ICRCC is not equal to 0, arrays of elastic specific storage and inelastic skeletal specific storage will be read for each system of interbeds the recompression index and compression index will not be read. icrcc : int icrcc is a flag to determine how recompression and compression indices will be obtained. If istpcs = 0, an array with initial preconsolidation stress values will be read. The offset values will be added to the initial effective stress to get initial preconsolidation stress. If istpcs does not equal 0, an array of offset values will be read in for each model layer. istpcs : int istpcs is a flag to determine how initial preconsolidation stress will be obtained.

nn : int nn is the number of nodes used to discretize the half space to approximate the head distributions in systems of delay interbeds. If ivoid 0, void ratio will be treated as a variable. ivoid : int ivoid is a flag to determine how void ratios of compressible sediments vary in response to changes in saturated thickness. If ithk 0, thickness of compressible sediments varies in response to changes in saturated thickness. ithk : int ithk is a flag to determine how thicknesses of compressible sediments vary in response to changes in saturated thickness. nystm : int nsystm is the number of systems of interbeds. iswtoc : int iswtoc is a flag used to control output of information generated by the SUB Package. If ipakcb is non-zero cell-by-cell budget data will be saved. ipakcb : int A flag that is used to determine if cell-by-cell budget data should be saved. Parameters - model : model object The model object (of type :class:`.Modflow`) to which this package will be added. Class ModflowSwt ( Package ): ''' MODFLOW SUB-WT Package Class.
