Hello, It will be very useful if GMS display after a modflow run, the flow residual value and the head change value for each cell (grid values). The display must concern a given iteration and time step selected by the user (that can be controlled under Modflow / Output control command for example) In many cases, a few cells with great residuals values can affect the entire model. Currently, we can only see maximum values of head residul in the list file and it isn't enough. It will be more interesting to map these parametres and check them in gms interface (in post processing) Cordially
