  1. I am wondering if there is a way to get the porosity in the material properties to transfer over to the MODPATH porosity array. My model is somewhat non-linear so I have to use NWT with upstream weighting and i created the model with solids created from rasters created in EVS so i don't have coverages to do a Map->Modpath command. Any help is appreciated.
  2. I am running a transient MODFLOW scenario using the NWT solver with UPW. We are doing significant dewatering in this scenario and the water is drawn down through several layers (necessary due to geology). The MODPATh model will run for a while and then crash due to "cell thickness is negative in" some cell. I believe particles are entering cells where the CHD and NWT have the water table below the bottom of the cell which is causing MODPATH to crash. Is there any way to fix this? I already have MOODFLOW outputting head at the end of every timestep and the IPHDRY set to a positive number.
