  1. 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.
  2. GMS Crash converting shape file to UGRID

    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 successfully. Restarting the machine, as well as trying a different PC doesn't appear to have much effect. Cheers
  3. Adding a shape file (ArcMAP) into GMS - Layering onto a TIN

    The shape files I have (and there corrisponding TIN's) have depth data, yet I am still experiencing issues with adding each geological layer to the model. Ideally, I wish to place 8 geological seams within 19 layers (the surrounding layers will be generic due to their complexity), they are not laterally continuous and therefore I think USG would suit the needs of the model best yet am struggling to embed the provided data. Would anyone know of a guide to utilising GIS shape files as MODFLOW layers?
  4. I'm trying to find a suitable work around for modelling flow pathways through abandoned mineworkings, some of which are above the water table (dry) and therefore subject to non-darcian flows. My data, however, is a blanket of worked seams and lacking any tunnel or shaft data (the hope was to use CLN utilising this network data). I am hoping someone may have some experience with battling similar issues? The data is all vector data used in ArcMap and I've noticed that some files will transfer into MODFLOW easily (such as DTMs), yet others like TINS do not. During the initial process, I have a few questions I hope someone with more experience may be able to answer. 1) How to site the workings at their respective heights using Arcmap shape files and TINs. (MODFLOW doesn't seem to like TINS but does recognise them). The shape files are divided by 20-50 meter barriers of solid seam (walls of major blocks), would this kind of shape file transfer when placed into MODFLOW easily distinguish between Open channel flow for the known workings, and a general value for the aquitard wall materials. 2) Once the workings are in place at their respective depths, is there a way within GMS to allow all surrounding lithologies to be generalised (i say this as the local geology is cyclotherms and is made more complex by the inclusion of coal mineworkings). I've included the 3D geology image below, exhibiting the space between the coloured seam workings. 3) Would the easiest way to produce connecting shafts between the various seams be by using wells? Thanks in advance, M
  5. Importing TIN's (ARCMAP .adf) into GMS

    Thanks very much Michael
  6. Importing TIN's (ARCMAP .adf) into GMS

    Hi all, A bit of a simple question but I can't find the answer anywhere in the help files. I've been provided with some ARCGIS TIN's (.adf files within the TIN folder) and I'm struggling to import them into GMS. Is there a conversion that must be completed before this will work or am I missing something really simple as GMS just spits out errors at present. Thanks in advance M
  7. Hi Guys, firstly I'm quite new to the program (MODFLOW) and I am looking to develop a model of abandoned coal mine workings to potentially store flood waters within a city. From working through the tutorials it would appear that MODFLOW-USG Connected Linear Network (CLN) is the appropriate technique (but would appreciate clarification on this). Would anyone have any experience with modeling non-darcian flow networks (Eg Karst or man-made voids) who may be able to provide some valuable insight into the process? Thanks in advance M
