Billy Aguirre Pozo Hydrogelogist Modeller

Hi Everybody.

I built a model on transient state with 4748 days of total simulation, all was going well when the time step size, gets freeze running with a small  time step (example, 0.33 days), what could be happening, i try all everything changing numerical parameters, time series, but nothing. Any ideas please. Help with this issue. Thanks.

Hi Everybody,
How can I calibrate a model using FePEST (Smooth PEST++), indicating a minimum %RMS value (objective function). The Phi value could be expressed in function of the %RMS value. or I have to setup a different way using Montecarlo Criteria.

Hi Everybody.

How could i add some baseflow data from a river, to get a good calibration for recharge distribution on FePEST, is there a possibility to do that (On Steady & Transient State). I have read that can be possible with budget rate flow charting, but I'm not sure how to accomplish this due. Thanks for ideas and help.

Hi Everyone.
I'm focus in a rescent project that represent the dewatering process for a mine, but i built a mesh starting from a layered mesh, using nodal distribution for a each pit stage with 3D configurator, the final mesh has large  number of elements and nodes, aproximately >4000000 elements, considering that fact, i was looking for a solution and i saw that the best way is to use a vertical refinement like the image on this post. how to do this workflow to accomplish this due, i will appreciate some ideas, thanks.

Hi Every body.
Rencently i was testing a basic model with the recent version fo feflow 7.5, and when i want to asign a multilayer well boundary condition, by link to parameter from a excel file, there is a error that i cant understand, it shows a message "FIELD NOT FOUND". i was thinking that it maybe is because it needs a field with the number of node but, not i was trying to change many options, but nothing, is there a problem with this version?. many thanks for help plaese. :-[
