  1. Is there any documentation on the n/m offset that can be applied to SX boundaries? Table 7-5 has the following entries: Flag f : SX: n offset for determining cell invert levels for distributing flows. Flag D : SX: m offset for determining cell invert levels for distributing flows. I can't see any other information on this in the manual or on the forum. What is it intended for and how does it work? Thanks!
  2. Q: In ESTRY is it possible to apply a QH rating in the channel. Not as a downstream boundary, but in the middle of a reach to act as a control representing a structure in the channel? A: In regards to QH ratings in channels, there are two different methods: • M Channel (section 5.8.1 of the 2016 Manual) The M channel uses a matrix of QH relationships to define the mechanics. You can also read the description in the manual but I’ve coloured up my example csv for easy reading below. There are a few rules with the flow values: the matrix must be square, it must have the centre line of diagonals and it must be negative (or zero) below the diagonal and positive (or zero) above. • Q Channel (Section 5.8.2 of the 2016 Manual) This uses a Depth Discharge curve, like you would for a pit inlet. The H values in this case are for the upstream end of the culvert. In deciding between the two of them, I’d have a look at the culvert and the flow regimes you expect. If you think that the culvert will have significant downstream control, then an M channel is the better option. If it’s pretty much always upstream controlled, then you may be able to get away with just a Q channel.
  3. Hi, I am trying to produce a time varying long section plot along an ESTRY (1D) branch in my 1D/2D model. Using the Excel macros I can plot the water level at either the start or end point of a branch versus time and using the miTools I can plot a long section of my branch. Yet neither of these seems to offer me a way to display the water level along my branch (and with the correct longitudinal distance) at a particular time. Is it possible to do this and if so how? I have attached a picture that gives an idea of the kind of output I would like to produce. Thanks in advance for any helpful suggestions or comments. Regards, Franciscus
  4. Hello I have an ISIS-TUFLOW model with ESTRY channels that link to TUFLOW (but not ISIS). When the model becomes unstable in the ESTRY component the ISIS run does seem to acknowledge that the TUFLOW component is no longer valid and it just sits while ISIS continues. CTRL+C will not terminate the TUFLOW component and formally closing from ISIS is not reliably an option. The general outcome being that final results files may not generated in the ESTRY TUFLOW component making trouble shooting more difficult. When running a batch this also means that the next run cannot start without manual intervention. Can this be addressed? Thanks, Ellie
  5. Hello Probably a fairly simple question but has been driving me round the bend. I am trying to convert a short 1D reach from ISIS to ESTRY and use the XS Database command to bring cross-section data in from the existing ISIS file. I have specified the ISIS.DAT file using the XS Database comment and produced a short 1D_NWK file (S Channel), the properties of which I would like to be taken from the specified ISIS .DAT file. What I am unclear on is how to specify the ISIS section to use at the upstream and downstream end of the network channel. Previously I have used the 1d_TAB file to point at ZX csv files. Any help gratefully received!
