  1. Hello, For a very long time, I have been trying to create a numerical model of an aquifer with complex hydrogeology (by using borehole-to-Ugrid option). I had several layers of 4 different materials. But all my efforts were trash. Because, I have never obtain a successful Modflow-usg run. They never converged. Although wetting option was on, the aquifer had so many dry cells. And these dry cells were always at same locations (not near/at the location of wells). It was meaningless. I couldn't run the PEST. So I decided to make my system more basic and created a one-layer model with HK zone
  2. Hi there, I'm having a problem related with assigning specified flow boundary conditions to my UGrid / Modflow-USG model. The error appears when I do the '' Map to MODFLOW'' option while converting my conceptual model to UGrid numerical model. I have read the helping document saying that If you want to use ''Specified flow boundary condition'' the UGrid must be a stacked grid. A stacked grid is one in which there is no vertical discritization of layers and the horizontal discritization of all layers is the same. (i.e. the Index of Vertical Sub-Discretization (IVSD) in the UnStructured Gr
  3. I'm trying to convert a series of shape files to Ugrid, some files convert within a second, however, 5 do not and crash the GMS software, only sometimes offering up an error message of the following: This machine does not have enough memory to continue this operation. Save your data and exit. (xms::CMainGMSFrame::OnCommand) Ive monitored my PC when running the conversion tool and memory never really spikes during the process. I also noticed that the crash isn't dependant on the size of the shape file with both larger and smaller files crashing when compared to those that converted success
  4. I have a number of geological layers as TINs. They are situated at their respective depths yet when I attempt to highlight them all and convert to solid or UGRID they create multiple grids (or solids) for each layer (TIN). As I am new to the MODFLOW package, what is the simplest process for turning TINs (some do not cover the entire extent of the model) into a 3D block to model groundwater flow via particle tracking. I have attempted fill between tins and horizons, however, nearly all solids appear as below, mishapen and not extruding between the TINs as expected.
  5. Is there a way to split a UGrid layer into multiple layers in GMS 10.0 or 10.1?
