  • Fixed a bug that prevented the Layer Property Flow (LPF) package to import native MODFLOW input file correctly when the wetting capability is used.
  • Fixed a bug that prevented the Time Variant Specified Head (CHD) package to import native MODFLOW input file correctly when the first lines in the input file start with #.

01/25/2016 Version 8.044

  • Fixed a bug that prevented the Stream-flow Routhing (STR1) package to work correctly with MT3DMS/SEAWAT.

05/20/2011 Version 8.013

  • Fixed a bug in PMPATH. When a heterogenious porosity field is used, incorrect pore-velocity values are calculated on cell faces based on average porosity values of adjacent cells. This version has been corrected to use the porosity of current cell instead of average porosity between two cells.
