3D discharge input files via ".pliz" for Delft3D-FM in Delta Shell

3D discharge input files via ".pliz" for Delft3D-FM in Delta Shell

Youngling Posts: 9 Join Date: 5/24/16 Recent Posts
In trying to test the 3D functionality of Delft3D FM in the newly released Delta Shell interface (currently in beta), we are trying to implement an outfall discharge to a given depth, (for example, discharge from an outfall into the bottom layer of a 6 sigma layer model). The user’s manual says that a “.pliz” can be used for this purpose where we specify the X,Y and Z, assigned to the discharge. As such we are trying to use “.pliz” files to represent discharges into the model. But in trying to do so we are running into some problems with the new Delta Shell interface.

In Delta Shell, it is required that the whole project be saved as a “.dsproj” before it can be run. When doing so, Delta Shell, auto generates a “.ext” file and wipes out all of the “.pliz” files that were assigned in the original “.ext” file. I am wondering if there is a way around this, or is there a specific naming convention that comes with the new Delta Shell to define 3D discharges.

Any help in this matter would be much appreciated.

Dear Abdulla,

Just to double check with you, are you aware that DeltaShell does not support 3D functionality, therefore, currently you may face some inconveniences when experimenting with 3D models within the New User Interface.
Knowing that you can as a beta user test certain functionalities directly via DflowFM.
Concerning your issue I believe that if you replace *.pliz files with *.pli files the export function should work properly.

Kind regards,
Michal

Hi Michal,

Again I would like to thank you, for your prompt responses on this forum. It is very much appreciated.

As I mentioned in my earlier post, I am trying to implement a flow model in the newly released Delta Shell, where I am trying to have an outfall discharge into the bottom layer of the model.
As a test I have setup a simple model with 10-sigma layers. I want the discharge to go into Layer 1, which would be the bottom for D Flow FM if I am not mistaken.

I defined a water level boundary on the left side of the model, and the discharge is implemented to the right.

I am attaching my model here, and I was wondering if you could take a look at the input files to see if I have set things up correctly so the discharge is going into the bottom layer.

Eventually I am trying to setup a Water Quality model with the hydrodynamics data from this model. I am also wondering if the ".hyd" file that is produced in delta shell is compatible with the Delft3D 4.01.00. I tried opening the ".hyd" file I got from D-Flow FM delta shell for the above model in Delft3D 4.01.00 and somehow the left side boundary definition did not seem correct, and I was having trouble fixing this. If you could please let me know any information regarding this I would appreciate it very much as well.

thank you very much,
Abdulla,
