Hi Agacija,

The simple answer is no. There is no tool that merges two res11 files and generates only one file with the content of both files (as far as I know). But, there is a more complex answer , too. You have two options, depending on the context:
1. As Craiggoo said, you can load both files in Mike View and make some plots an so on using information from both files.
2. You can add results of your simulation to an existing result file. This can be done by open the Simulation (*.sim11) file, go to "Simulation" tab, at the section "Initial Condition", for HD model select "Hotstart" as "Type of Condition" (the same for the modules AD, ST, RR). Now, you can select an existing RES11 file (in your case, the file which contains results from 2000 to 2008) and check the checkbox button "Add to file".  At this point, you can run the simulation for the next period (2009-2016). As you may observe, this solution is possible only if you have the model and data to run again the second period. Also, you may want to have a continuous time axis for your results, so the two periods should be right next to each other.

Hi suruchigeo,

The problem is that the boundary you specified in bnd11 file is defined as Open for chainage 1526.960 and this point is not actually at the most upstream part or most downstream part of your branch(river). In fact, you can have maximum two open boundary conditions for a branch.

If you describe more detailed what you want to do, maybe we can give you a more detailed solution. Until then, I suggest you to use in the upstream part of your river(branch) Inflow discharge and in the downstream part Q-H relationship if you don't know the variation in time of the water level at that specific point. If your river ends up in sea or in a lake, you can probably use WL open boundary condition (as constant or as a time series), or in any other cases when you know the water level at the downstream location.

Can you, please, describe with further details the structure you want to model? It would be also helpful to attach a schema or a picture. Anyway, if the water can overtop the structure you need a weir to simulate this.

Hi,

I think it's enought to use control structure. In fact, if you define the struture also as culert, you will end up with to independent culverts, one with gate and another one with free flow.  Thus, this second approach is wrong.

If you think the culvert is too long and you want to use a branch to schematize it, you have two options:
1. If entire flow passes throw this culvert, than use two close cross-sections on your branch at the start and at the begining of the culvert. Set up a control structure between this cross sections to control the discharges;
2. Use a separate branche delimitated by close cross-sections. On this branch you can place a control structure.

Good luck!

Hi,

I've just tested the API for reading two dfs0 files. The first one was extracted from file with the default hydrodynamic results ("results.res11") and the second one from the file with additional HD results ("resultsHDAdd.res11"). Both files are very large (218 Mb, respectively 600 MB).

Everything went fine with the reading of the file. I found all the time series for all the nodes which should be stored in each of the files.

I hope you already know that in the default results file generated by Mike 11 from hydrodynamic models you get discharge time series in discharges nodes and water level time series in corresponding nodes. If you want to get discharges time series in water levels nodes, you have to use additional hydrodynamic results, named "....HDAdd.res11". To obtain this file after simulation, you must check (before running the model) some options in HD Parameters file, under "Add. Output" tab.

Hi amarburg,

I think the points you've mentioned are not computational nodes. Those points are used to describe the geographical / physical path of the river branches. In most of the cases, the number of this type of points is bigger than the number of computational nodes.

Anyway, thank you for your post. Maybe, this discussion will clarify some aspects of this subject.

Kind regards,
Aurelian

Hi Mathieu,

I found the option which could be used as argument for res11read.exe in order to get the XY coordinates of the grid points and this is "-xy" (for all grid points). Thank you very much for your helpful indication.

I'll write below the content of the batch file which i used:

set PATH=%PATH%;C:\Program Files (x86)\DHI\2012\bin

set res11FilePath="%CD%\RiverX.res11"
set outputFilePath="%CD%\RiverX (XY-AllNodes).txt"

res11read.exe  -xy %res11FilePath% %outputFilePath%

Hello,

Does anyone know how to get the geographical information of the computational nodes (grid points) from a  Mike 11 HD model ? In other words, is there any way of exporting the computational nodes of Discharge and Water Level to a shapefile ?

Thanks,
Aurelian

Hello Sumit,

If the only significant influence of the tides in your river model is changing the sea level which has important influence in the downstream part of the river, the solution is to use a water level hydrograph as a downstream boundary condition.
