I've created an IFM that produces data to be used by FePEST.  It saves it in a *.fpo file, which PEST can read.

Is there any way for my IFM to know when the model has been called by FePEST, and for it to know which directory is the current PEST working folder? I'd like to be able to save the .fpo file in the current PEST working folder where PEST will find it.

When I open one model, the Conductivity defaults to m/d, whereas another model defaults to m/s.

How can I change the default?

Hovering the mouse over the units on the Assignment Toolbar lists what is available, but right clicking there and selecting 'Units' (or going to Tools>Units) doesn't allow defaults to be changed.

In the View Components panel, various display options can be changed (such as number of decimal points, and colour scheme), but not the units used for display.

Answer:
In the Data panel, the default units can be changed by right clicking on the data types K_xx, K_yy, K_zz. Each one needs to be changed separately.

:( my model is 3D so if it works in 2D only then that means I need to go back to a very early version of my model and rebuild much of it.

Ideally, I would have made elements inactive rather than deleting them (as then I could reactivate them), but I didn't get the active/inactive data type until after I'd deleted an element and locked the mesh.

If I currently have a 3D standard saturated transient model with a free surface, is there a way to access the active/inactive elements data type without deleting elements and locking the mesh?

Is there a way to re-add/fill holes in the mesh where I deleted elements. I don't want to remesh the whole model as then I'll lose boundaries and discrete features etc.

Hi Peter,

Will the online IFM reference be updated to reflect the new 6.2 functions?

Lakes.

If only FEFLOW had a native way of modelling them, our lives would be so much easier....

Hi,

When trying to refer to chart functions such as IfmCurveCreate, it seems that I need to add in a reference to ifc_diagram.c, but when I do that I get compilation error stating that several functions are being redefined in various places. Mainly it's conflicts between graphic.h and intrinsic.h.

Is there a straightforward method for accessing chart functions?

(using Visual C++ 2010 Express)

When running PEST in parallel mode, BEOPEST uses a full core on the control PC. Why? It should be sitting idle, waiting for the servers to return results.

I would usually not import the DEM to FEFLOW, but keep the data in Arc.

Once you have your FEFLOW mesh, export the nodes to a point shapefile, and use Arc's "Extract raster to points" (Spatial Analysis > Extraction) toolbox function to assign elevations from your DEM to the points. Then import the point file back to FEFLOW (use ninverse distance interpolation using the nearest 1 node) to assign the elevations to the appropriate slice.

This method is usually faster than manipulating large masses of DEM data within FEFLOW.

If the water table always comes out as a flat line, then it usually means that the balance between recharge and hydraulic conductivity is wrong.

Increase your recharge. Or decrease your hydraulic conductivity. Or both. Now water will build up under hills. Make sure it can discharge at seepage/spring/river locations in valleys.
