This data release contains the MODFLOW 6 models described in the related Groundwater journal article (
https://doi.org/10.1111/gwat.13459). The models are generalized cross-section models of a hypothetical and idealized aquifer. The models are used to examine the effects of layered or full grid connectivity with and without the XT3D option in the Node Property Flow (NPF) package of MODFLOW 6. The data release contains the models described in the paper, the 6.5.0 binary executable for MODFLOW 6, the 6.5.0 MODFLOW source code, and the Python jupyter notebook and related Python utilities used to generate, run, and post-process the results.
