Aloha, I have been trying to use the horizontal anisotropy function to model an area that has many dikes of similar strike. I'm not exactly sure what GMS is doing, however, becaue I can not find any documentation, on forums or the wiki, about how this feature works with the MODFLOW LFP package . For example is the anisotropy always aligned with grid cells? Is there anywhere else to access the feature besides the LPF dialog? If anyone can point me to documentation about this, or can explain it I would be much appreciative! Thanks,
