[font=courier]getTimeSteps(...)
    Fetch list of time steps stored in the current DAC file.
    SYNTAX: <list_of_steps> getTimeSteps()
    RETURNS: a two-dimensional array of time steps
            index 0 contains the simulation step number (may be different from index on sparse DACs)
            index 1 contains the simulation step time[/font]

However my output looks like this:
[font=courier][(0, 0.0, [b]0.0[/b]), (88, 3653.0, [b]3653.0[/b]), (139, 36554.0, [b]32901.0[/b]), ...] [/font]

What's the 3rd number in there?

Thanks, Chris

which version are you using ... I'm using a dfs2 file (Type Fraction, Unit ()) in a MikeShe 2014/2016 model and it's working just fine. Chris

res11read only works with res11 files, correct? I'm using the Mike1D engine which stores results in res1d files. It doesn't seem that a similar extraction tool exists for that format yet?!

I built a Mike11 network for MikeShe. When I run it in Mike11 it seems to be working ok (at least I didn't get any error messages). Once linked into MikeShe, the pre-possessor returns:

"Error: Cannot find dig- or H-point(s) of cross section no. ##; branch no. ##: ###; chainage: ###"

Can anyone provide some more insight on what’s causing this and how it can be resolved?

Thanks, Chris

yes, I noticed after posting, that though I'm building a MikeShe model, this is really a Mike11 question. Reposted there ..... Thanks, Chris

According to the documentation, MikeShe uses "the normal [vector] to the thalweg of the river" to calculated the correction angle for a cross-section. How exactly is that done?

Our cross-sections typically sit between 2 river segments (see attached image). If the cross-section was developed from a DEM (instead of a survey), we assume its direction to be perpendicular to the "average" direction of the upstream and downstream segment (green cross-section perpendicular to dotted line). How would MikeShe calculate the correction angle for that? Base on the normal vector of one of those segments (which one?)?

Thanks, Chris

Just wondering: why are the different years in different models, and not all consecutively in the same model?

oh, don't bother exporting data and using Surfer or ArcMap - absolutely no need for that!

If you're trying to copy heads from one time step to a reference distribution: you don't need to export and re-import the data. I usually go to a 3D window, select all nodes, then right click on head and use 'copy', go to the nodal reference distribution and click 'paste' (see attached paste_to_refDist.png). Depending on your selections, you can also paste to one slice/layer only.

The easier way is indeed to reference a head at a specific simulation time as Adam has shown: Head - Head@(time). The drawdown gets calculated "on the fly" which means you can step through the results and see the current drawdown at any selected time.

Personally, I prefer to show the zero-pressure contour in 2D cross-section view: Establish your "initial condition" (steady state) and copy the pressure (instead of the head) to a nodal reference distribution ('Steady State Pressure'). Add this reference distribution to your cross-section view as one contour of value 0.0. Then also add the zero isoline for pressure. Start your transient simulation including your pumping (stress) and watch how the current watertable (zero isloline of pressure) relates to the steady state condition. See crosssectionview.png for an example.
