Hi all, Using the option "use screen" for "wells" in sources/sinks, am I telling the model that the water extraction is only carried out in this interval? When I turn on this option GMS transforms my extraction wells in injection wells!! Why is that? Is it a software problem? Best regards Filipe Miguéns
Hello everyone, Can someone tell me if there's a limited number of observation points using MODFLOW USG? I have 77 observation points for my model, but when I create the files in GMS it considers only 7 of them! I started my model from scratch using MODFLOW-USG, so I cannot import the 3D Grid files as exemplified in the tutorial. Another thing that occurs in my model after running it, is that the observation targets don't show the same value as the generated head surface?! Can you help me? Best regards Filipe Miguéns
