DFM Output error

2021-08-02T20:07:50Z

Hi,

I was wondering if someone has been able to succesfully use the dfmoutput tool on a Linux cluster?

I am currently working with DFlowFM/2021.03-67911-intel-2018b on Cartesius. I receive errors about the version when I try to merge my partitioned _map.nc output and restart files respectively (see attachments). This confuses me as I am using the same version as I have used to generate the partitioned output.

I have followed the instructions in the manual and created a .txt file with all the files which should be merged.

I would greatly appreciate if someone could inform on how to use this tool succesfully.
Thank you in advance.
Best Regards,
Luka

Wave model cannot be initialized, error code -1

2021-07-22T02:53:42Z

Hi,

I am running an given example wave model with Delft3D FM (2021.03). The model can be validated but after running the model, the initialization of waves fails because of Error code -1 and it did no generate a diagnostic file. The run report does not give much information too.

I am sure the model is set properly since it is a example wave model, and my colleague was able to run the same model just fine.
Does anyone know what this error code means? Is there a way to diagnose and fix the problem?

Thank you in advance.

Please try to install the new release (2021.02). It might fix your problem.

Delft 3D FM will not run

2021-07-15T05:46:50Z

I am using Delft 3D FM 2020.02 version 1.6.1.47098. On my desktop . The model gets validated , however it will not run. I have tried running it on a separate installation on VMWARE instance and it runs success fully. I am totally what is the issue on my desktop. I have attached a log file. There are several errors regarding access of the file, missing .dll, remote procedure etc. Any help will be appreciated.

RE: Initialization error reading old-style forcing file

2021-06-22T07:51:31Z

Dear Coby,

In the 'regional_bnd.ext', the quantity of the first boundary condition is missing. I hope this solves your error.

Additionally, Delft3D FM can have issues with working with both the old and the new style external boundary conditions. Thus, if your model is still not able to run after implementing the quantity, please use only the old style or only the new style external forcings file.

Kind regards,
Tjitske

RE: Open Earth Tools Errors

Hi Chris
If you are trying to use Dashboard in Matlab, first you should load all the EOT functions in your Matlab session. My advice is to use the next Matlab functions:

1	addpath(genpath('PATH WHERE EOT FILES ARE DOWNLOADED'));

For example, I have the EOT folders in C:\DeltaresTools\EOT
Before to use Dashboard, Muppet, Quickplot, etc. in my Matlab session, I write in the Command Window:

1	addpath(genpath('C:\DeltaresTools\EOT'));
2	oetsettings;

Kind regards.

Initialization error reading old-style forcing file

2021-05-05T21:56:41Z

I extended a model's mesh and converted/extended the inputs (winds, boundary conditions, bathymetry). The previous model works fine, but the new model gives this error while initializing:
** INFO : Opened file : regional.ext
** ERROR : Expected property quantity for boundary definition
** INFO : Closed file : regional.ext

I don't have any boundaries defined in regional.ext. Has anyone troubleshot this error before?

RE: Unable to Import and Interpolate Bathymetry

Hi Michal (and everyone else)! I just wanted to give a quick update on this issue as I have resolved it myself, and I'm sure others will have similar issues in the future. The core of the problem is that we were extracting the .zip drive of the install files into a folder which was backed up by Microsoft OneDrive. We installed the actual Delft3D software into our Program Files (x86) folder which is not backed up by OneDrive, but just having the install files backed up in the first place was causing all of our issues.This caused a host of issues that were not replicable; even from repeat installations on the same machine. Therefore, the solution was to install the Delft3D installation files directly onto the C:// drive and make sure it isn't backed up by OneDrive (and I'm sure that Google Drive and other services might cause similar issues).

RE: Unable to Import and Interpolate Bathymetry

Hi Michal,Thanks for your comment. I have utilized versions 2021.03 and 2021.02. 2021.03 had a separate, also critical issue which prevented me from using it. I've emailed our support personnel to see if they can provide me with 2021.04 - we are paying for support, so hopefully we will have access to the beta version.

Dear Matt,
Sorry to hear about your troubles. Do you have access to one of our more recent releases? The latest Generally Available version is 2021.03, if you are part of our Beta Testing Program I would strongly recommend to use 2021.04.

In both versions there is quite significant amount of improvements around importers, stability as well as we tried to make communication with users more verbose. Could you please try with the newer version and lets us know how it goes?

Kind regards,
Michal

Unable to Import and Interpolate Bathymetry

2021-04-08T22:26:05Z

Dear Delft3D Community,
I am getting an error when trying to import bed levels to interpolate xyz data onto my grid. This is a problem for both xyz files I’m developing for my project, and the tutorial files as well. I’m using “tutorial 4” (Section 4.2.5 in the manual) to troubleshoot. When I try to follow the following instructions from Section 4.2.5 of the manual:

Import a sample file containing the measured bed levels: in the drop down menu at the top of the screen (See Figure 4.15), select the Spatial Operators menu, choose layer Bed Level, click on Import

I receive the following error in the attached log file. I am using Delft3D-FM version 2020.02 on a Windows 10 machine with the following specs.

Dell Precision 5550 - Intel i7 processor (version 10850, 6 cores) a 32 GB of RAM.
Windows 10 –10.0.19041 build 19041

I’ve pursued the Delft3D forums and Googled the problem but am unable to find the source of the issue or someone else with a similar error. I've also tried uninstalling and reinstalling Delft3D-FM numerous times, with no success. Is anyone else facing this challenge right now? Obviously this is a critical error that's preventing me from performing even the most basic analysis with Delft3D-FM.

RE: Create netCDF from a text based triangular mesh with(out) Quickplot

2021-03-30T19:12:40Z

Dmitry: "in the Delft3D-FLOW (structured), there was an option to plot temporary inactive water level/velocity points. They could also be added to the plot as a foreground layer, to show dried (flooded) areas."
Yes, that's correct. The Delft3D-FLOW output has a dedicated reader which adds such features based on the related dry/wet flags for the velocity points. The D-Flow FM results are processed by a generic netCDF file readers and hence largely treated as a netCDF UGRID file of arbitrary origin; furthermore, it doesn't include specific dry/wet flags, so threadholding the water depth is the only option.
The patches plot has a special option "colour uniformly" which might be used for this type of use case, but it seems that I'm currently always clipping the zero values such that this feature can now be used to mask/colour the flooded areas, but not the dry areas. I'll check whether there was any specific need for that clipping; if not, I'll remove it, such that you have full control using the value clipping. That will allow you to use the feature as a dry areas overlay.

Thanks Michal. I've already tried qgis_umesh plugin developed by Jan Mooiman. This is a nice tool, I like it.

Ah I see. Thanks very much, Bert, for the detailed explanation. This was extremely helpful. I'll give that a go.
Just one thing: in the Delft3D-FLOW (structured), there was an option to plot temporary inactive water level/velocity points. They could also be added to the plot as a foreground layer, to show dried (flooded) areas.
Best,
Dmitry

Hi Dmitry, A lot is possible, but I'm not sure I understand exactly what you intend to visualize; I don't see how your figures show drying and flooding -- I think that I'm looking at a figure of the water depth. FM can also write out the water depth to the map-file and you can visualize it and optionally clip (make transparent) the cells for which the water depth is below a certain threshold. If you want to color the dry cells light blue then you have to add that as a first layer to the plot. You can either plot the grid (not hiding what is on the background map within the cells that are sometimes dry) or you can select the quantity "Topology data of 2D mesh - face indices" and select "Colour uniformly" and select light blue. Create the plot. Add to this plot the water depth plot with areas with water depth below for instance 0.01 m clipped (transparent). That should give you a figure that looks similar to your figure if I interpret it correctly. If your model is bigger and actually included the whole sea area on the right, and you intend to visualize only the area that is initially dry, then that's also possible. In that case you'll have to select the 1st time step of the water depth and define a variable, e.g. "initial water depth", via the button on the bottom row of the QUICKPLOT dialog. Subsequently, you select All time steps, and define another variable, e.g. "all water depths". Then you select from the list of opened files, the option "<user defined variables>" and open the "file dependent options" dialog by clicking on the 4th icon in the toolbar. There you can select at the top "all water depths", as operator "A under condition B", then you select the "initial water depth" and as condition you specify "<0.01" (no space between < and 0.01). For this you define the variable "water depth where initially dry". Return to the main dialog and now select this variable from the user defined variables list, and visualize it. This shows you the water depth where there was initially no water, e.g. ideal for coastal flooding.

Dear Julius and Dmitry,

You can also try:
"QGIS plugin to plot 1D, 1D2D and 2D time series map results as animation"
that one of our colleagues developped:
https://github.com/Deltares/qgis_umesh

If it proves useful, your feedback and suggestions are very welcome!Cheers,
Michal

RE: Create netCDF from a text based triangular mesh with(out) Quickplot

2021-03-30T14:36:06Z

Great animation! I will check that tools, thanks! But I mainly had in mind plotting areas where drying/flooding processes occur (screen-grab attached). According to manual, drying and flooding is implemented in D-Flow FM, but I still cannot find the way to represent it graphically.
Kind regards,
Dmitry
