  1. Hi Phillip, Thanks but I have already done this. Cheers
  2. Hi, MapInfo/miTools is telling me I have not correctly specified the location of excel.exe in the Path_to_Excel.ini file, and thus will not produce a longitudinal profile for me. I have downloaded the most recent miTools update from the Tuflow website, and specified the correct location of the excel.exe file- does anyone know why this function is not working? I am working with Excel 2007 but I assume this would be taken care of with the most recent miTools update? Thanks
  3. Thankyou Richard, Phillip for your suggestions. I thought I'd share my response to the problem: Whilst the 1d storage basin (represented as a pit with an NA table, connected to incoming and outgoing pipes in the 1d_nwk) appeared to be working without instability, the flow hydrograph through the basin seemed very unusual (extreme oscillations). However the stage hydrograph of the 1d basin showed reasonable operation when compared to the 2d stage hydrograph (obtained from a PO point on top of the basin)- that is, peaks in the 2d water level followed 1d pit surcharges. Osciallations in the pit flow hydrograph may be attributed to the rapid filling/emptying of the basin (the basin is fairly small compared to the flow over the floodplain) and the associated behavioural changes in connecting pipes. So for anyone else modelling a similar basin, I'd suggest comparing the stage hydrographs in the 1d and 2d alongside the flow hydrograph. Cheers Chiara
  4. Thanks for that Richard. The basin is connected to the 2d domain. The NA table I have applied to the basin does take into account it's shape.
  5. Hi, I am attempting to model a storage basin within a 1d network, connected to a 1d stormwater network, within a 2d model. The basin is triangular in shape and has 1:4 side slopes. I have created an NA table for the changing surface area with elevation, and applied it to a 1d_nwk pit (type R at the moment, since there is no option for triangular pits). The model runs without instability but the hydrograph of the 1d basin is all over the place. Any suggestions? Thanks!
  6. Just to clarify, I am trying to snap CN lines (within the 2d_bc_hxi layer, where the 2d_bc (HX) boundary also lies) to the 1d_nwk.

  8. I am modelling a 2d floodplain, flowing out to a 1d channel (hypothetical channel created as 2d boundary was crashing for large flood events). MapInfo will not allow me to snap the 2d_bc_hxi (HX) line to the 1d_nwke. Has anyone had this problem? In previous TUFLOW models I have built, using MapInfo as the GIS software, I have not had this problem. I have tried minimising the snapping tolerance, but to no avail. I have also included a "Snap Tolerance" function line in the .tcf file. It seems that MapInfo is only 'truly' snapping nodes together if they are in the same layer. Any help? Thanks
  9. I have a 1d/2d model with the 1d_nwke extending beyond the downstream end of the 2d_bc_hxe boundary. Is it possible to use the automatic HQ function when applied to the 1d_nwke (i.e in a 1d_bc table) at the downstream end? The manual only describes the use of the automatic HQ function when using it as a 2d_bc boundary condition.
