  1. Thanks to Hydrology and Kirk for your contributions . I never experienced any problem with a number of stress periods < 1,000. I think time steps are not counted in this number, but I never tried. Maybe any supervisor of this forum can answer the questions: Maximum allowed number of stress periods (number of time steps included or not?) within the current version of GMS? What about this special compiled Modflow version allowing up to 10,000 Stress periods which was mentioned in an older thread? Thank you. Regards Markus
  2. Hello, by default the maximum number of stress periods in modflow 2005 is/was originally 1,000. Is this still valid within GMS? In an older thread it was mentioned that there is another compilation of modflow available which can handle up to 10,000 SP. What is the current state? Thank you. Regards Markus

    UZF package

    Hello, I have a 5-layer model, 230 kmĀ², uniform 50*50 m cells, 168 stress periods. LPF, RIV, SFR2, WEL, DRN, ET, UZF (RCH), PCG, MODFLOW-2005 The model is running fine using RCH with time variant and spatially distributed infiltration rates. Due to the fact that the modeled area has significantly varying groundwater distances within the range from 0 to > 100 m with correponding time series of groundwater heads, I think it is a good idea to use the UZF package. NUFZTOP=2 (3 does not work, input of array vks is not possible) IUZFOPT=2 (vertical conductivity is 5E-06 to 5E-05
