Cavalera 0 Report post Posted May 4, 2016 Hi, If I use the auto-assign function for implementation a "Specified flow = 0 " to cells (for example along an arc) it appears like a "Well condition" in GMS. Is it the way that Modlfow deals with this boundary condition or it is a implementation of GMS ? Can you precise this ? Quote Share this post Link to post Share on other sites
Hisham 0 Report post Posted May 4, 2016 The default is now flow, so you don't need to assign a BC there. If you do then it shows as wells with zero flow! I struggled with this first but then got used to it. Hope this helps Quote Share this post Link to post Share on other sites
