2.1.5 pre- and post-processing issues

RE: Bathymetry inverted

2023-07-15T15:50:38Z

It seems like you're encountering a puzzling issue with the bathymetry data while working with Delft Flow FM and Delft 3D. The values appear to flip, particularly at the edges of the grid, where the highest elevation should be observed. This anomaly also persists when importing the bathymetry into ArcPro. While I don't have a specific solution for this problem, it's possible that the flipping of values could be attributed to a data processing or transformation issue.
In situations like these, it's helpful to consider various factors that could contribute to the problem. One potential area to investigate is the data transformation process itself. Check if there are any steps or algorithms involved in the conversion, interpolation, or exportation of the bathymetry data that might introduce unexpected behavior.
Additionally, since you mentioned working with Artificial Intelligence (AI) and the Internet of Things (IoT), it's worth exploring if any AI or IoT components are involved in the data processing workflow. These technologies can sometimes introduce complexities, especially when integrating different systems or automating certain tasks. Reviewing the configurations and settings related to AI or IoT aspects could reveal potential causes of the flipped values.

Error in exporting depth averaged velocity in QUICKPLOT

2023-06-27T14:38:23Z

Hi,

I am trying to export depth averaged velocity from a map file using quickplot. I am able to view the plot. But I am not able to export to time series CSV.
I get the following error

Catch in d3d_qp\exportdata
Function is not defined for 'cell' inputs.
In private\qp_export at line 434
In d3d_qp>d3d_qp_core at line 1804
In d3d_qp at line 43

Can you please guide me as how I can extract the depth averaged velocity using quickplot?

Thanks
Venkat

I think it must be because of this: Error retrieving FM Dll version: Could not find / load dflowfm.dll.

DELFT 3D FM SUITE : Error when running FLOW3D RFGRID

Hi everybody,
When I try to open RFGRID by clicking on "grid" on a flow3D FM model on DELFT3D FM Suite, I have this error :

On wave model, when I open RFGRID everything worked.

Do you know where the error come from ?

Thank for your help.

RE: "Error in mclFreeStackTrace" Quickplot

2023-03-06T15:02:32Z

Hi,
I routinely encountered this issue and this is my routine before opening the quickplot.
Open this directory "C:\Users\{User Name}\AppData\Local\Temp\{User Name}"
Then delete the folder named "mcrCacheX.Y".

After this, I can open my quickplot without the {mclFreeStackTrace} warning.

Good luck, Munawir

Hi Marilyn,

I did not see any problem in your "after interpolation" data.
The flipped value actually had made the bathymetry in the correct convention for D-FLOW FM, since it assign the bathymetry value as ELEVATION where the "negatives are at the ocean."
Or please let me know if I misunderstood the problem.

Thank you - Munawir

Bathymetry inverted

2023-02-01T15:47:59Z

I brought bathymetry data into Delft Flow FM from Dashboard by converting the grid in FM Flow and then bringing the grid into Delft 3D and importing the bathymetry, and interpolating the bed level data onto the grid and exporting it to bring it into FM Flow. The bathymetry appears to be correct when I first import it into Delft 3D but then the values seem to flip. The edges of the grid (which are land) and should be the highest elevation are flipped to negative values. The bathymetry appears to be correct but with flipped values. Does anyone know why this might be occurring? I also have been bringing this bathymetry in to ArcPro in order to make a point cloud to hopefully re-shape the bedlevel to run simulations in Delft Flow FM but you can see that bringing in that bathymetry results in flipped values in ArcPro as well.

RE: Error Running Delft Dashboard With Matlab 2020a

Hi Angie,

you must download all the EOT folders and scripts. Delft Dashboard is a component of EOT; for this reason, if you did not download all the EOT scripts, you can not run Dashboard.

Actual Depths of Sigma Layers in Delft3D FM

2022-07-21T15:56:45Z

Hello Everyone,

I am working with a Delft3d FM output file (FlowFM_map.nc) with sigma layers, where I need to calculate the actual depths of each sigma layer for each element of the unstructured mesh. Not sure if there are any instructions on how to do this, but I made some assumptions and took the following steps to get the actual depths of sigma layers -

a. In the output file, there is a variable called mesh2d_layer_sigma which I believe represents the sigma layers as a cumulative percentage of the total depth (which is represented by a variable called mesh2d_flowelem_bl) for each element. I multiplied these two variables (mesh2d_layer_sigma X mesh2d_flowelem_bl) to get the actual sigma layer depths for each elements. Is it the right way to calculate actual sigma layer depths using these variables?

b. The mesh2d_layer_sigma has values in the following order: -0.83, -0.50, -0.17. Does that mean the first layer is located at a depth of (0.83 x total depth) below the mean water level (surface layer)?

c. If assumption b. is correct, does that mean in addition to the sigma layers, and water velocity components u (mesh2d_ucx) and v (mesh2d_ucy), the bottom layer is the first index, and the surface layer is the last index along the depth dimension of the array?

d. The depth variable (mesh2d_flowelem_bl) mostly shows negative values. Does the negative sign mean, the depth measurement is below the surface level (e.g. -7 m means 7 m below the surface level)?

I would really appreciate it if you share your thoughts on this

Thanks,

Mahmud

RE: Running Quickplot outside GUI

2022-07-18T23:12:25Z

Hi Ali,

Quickplot is a tool of Deltares Open Earth Tools (OET). If you did not use Quickplot via GUI, you would use Matlab and load OET -> Quickplot to visualize your results. If you have luck and Matlab is installed in the cluster, so you should download OET in the cluster and load it in Matlab; call Quickplot, and that's it.

Running Quickplot outside GUI

Hi Everybody
I have done a simulation on a Linux cluster, and since the output file size is huge, I want to visualize the results in the cluster. Is there anyway to run Quickplot in Linux?
Thanks.

Gabriel,

I am having the same issues with running Quickplot. I tried options 1 and 2 that you mentioned, with no luck. With option 3, I was wondering which ctf files need to be with the Quickplot exe?

I first had the issue after updating my Matlab, could that have somehow interfered? I tried uninstalling and reinstalling Delft3d 4/the MCR, with no luck.

Using ArcGIS to postprocess FM results

2022-03-01T15:03:40Z

Is there a way to post-process results from Delft3D FM simulations? I saw that there is a program called GISView but could not figure out if this program works for the flexible mesh model as well or if there is another way to process the FM results in ArcGIS

Is there a limit of griid cells?

2022-02-23T17:25:57Z

I've have a model setup and when I go to start it goes through all the checks until "Part V - initialisation & checking second part..." and then it seems to stop. I've run other models fine and the only thing I can think of is that there maybe too many grid cells. Is this possible?
