  1. Hi, I made a model with solids and materials in GMS and then I used HUF package to define uniform model layers (cells with same thickness in Z directions). in eahc layer I have about 62500 cells (50 by 50 meter each). now I want to add salt into model and run 2 simulation one with 200 year and one with 150 years. MT3DMS run in each takes about 1.5 hour for each one. for SEAWAT I set transport time step to 365 days (one year) but it changes to one day and it takes for ever to be finished! (it does not even give me how long would it take for the model to reach the resullts!) I thought having uniform layers will help SEAWAT to be faster! And one more thing, each model is about 20 to 30 GB! is there any way to make it faster? and lighter? I wanted to run SWI for faster calculation time but it gives me an error which says HUF layers are not compatible with SWI! is there a problem with my model layers? or HUF and SWI don't work together? is it possible to run SWI with HUF? is there any way to export the HUF layer data and use it in LPF? because the input files with HUF are different. there is only one big text file with all the data for HUF and it does not have data of cells! I could not find if they are compatible or not in Moflow USGS site ( https://water.usgs.gov/ogw/modflow-lgr/MODFLOW-LGR-Guide/index.html?package_incompatibilities.htm ).
  2. Tprogs:lag distance X and Y

    Hello to everybody!! I am using T-PROGS to try to simulate a complicated geological situation within a context of outwash glacial deposit, with silt clay with intercalations of sand lenses. I have some boreholes with information but in some cases distance between wells for a valid correlation are too far (ca 500m) therefore i was advised to use T-PROGS which seems to be perfect for problems of horizontal correlation. main groundwater flow from N to south (Y+ to Y-), distance along the groundwater flow between wells is from 50m to 450m, but i am having some issues: 1- while deciding the lag distances (strike(x) Markov chain) i would like to know what could be useful to put as max lag distance?? because i have no way to see if the values i am using are valid or not, only until the end of the whole flow model of mod flow 2- in the same manner while putting the lag distance of Y (dip (y) Markov chain) can anyone shed some light here PLEASE 3- besides, while creating the grid and the successive T-PROGS for the unconfined aquifers i want to have different materials within the same layer is this possible with the HUF, to avoid dry cells. THANKS A LOT IN ADVANCE FOR YOUR COOPERATION AND REPLIES ALEXANDER
  3. I am running a model and refined it using the pilot points and am using the HUF package rather than the LPF package as suggested in the tutorial. I am trying to import the optimum values back to the model and do not see a way to attach them to the associated material. I have tried running the model after importing the optimal values and I again get my initial huge errors as the pilot points were never imported. If you have any advice on how to import these values it would be much appreciated. Version is 10.0.11 Greg
