Availability of Delft3D FM Graphical User Interface (GUI) (free of charge)

2023-06-03T19:15:08Z

It was announced that the GUI for Delft3DFM would be available in June 2023. Does someone know how to get it? As probably the site is not updated but as per the announcement, the GUI is available as it is already June. Does someone know how to get it? Thanks

running delwaq2 in parallel

2023-04-04T17:17:30Z

"I'm running delwaq2 on Ubuntu 22.04 LTS using the precompiled binaries I received through the beta testing program, version 2023.01. I have been playing around with the NOTHREADS constant to see if I can parallelize the computations somewhat. While NOTHREADS does seem to change the number of threads assigned to the process, when I run the "top -H -p PID" command, it appears that only one of those threads is ever actually doing any computations. Do you have any advice?"

Problem in merging restart files (parallel run in Linux)

2022-11-07T13:42:09Z

Hi everybody,

I am going to make a merged restart file from the results of an initialization run.
I wrote the list of all *_rst.nc files in a text file. Then I used the following command in the Linux terminal:
dfmoutput mapmerge --listfile list_restart_files.txt

But I receive the following messages without any merged restart file.
Info: mapmerge: all input files are of old format.
Info: mapmerge: for *_rst.nc files, topology connectivity variables (except for "FlowLink") are not merged.
Warning: mapmerge: could not retrieve coordinates of net nodes from `WS13_new_04_0000_20130101_060000_rst.nc'.
Warning: mapmerge: could not retrieve ElemLink from `WS13_new_04_0000_20130101_060000_rst.nc'.

The Delft3Dfm version is 2022.03 and using a similar mapmerge command, I can successfully create the merged 'map' Netcdf file.

Could you please share your experience in this regard?

Accessing dflowfm via BMI

2022-11-05T19:02:42Z

Hi,

I am trying to use BMI to initialize the model via a fortran program.

I was able to successfuly test out the bmi-python library [https://github.com/openearth/bmi-python] with my compiled dflowfm kernel and the provided e02..._westerscheldt example.

However, I would really like to access the BMI exposed routines via fortran.

I was able to compile a test program as shown below and link it to the shared dflowfm library. But while running the compiled executable, I receive a segmentation fault error that doesn't tell me much. So any help on how to successfully make BMI calls to the dflowfm kernel via fortran is highly appreciated. Thanks in advance!

Source code:
program test_df_bmi
character(len=100) :: config_file
config_file = "/home/bmi-python/test_data/e02_f14_c040_westerscheldt/westerscheldt.mdu"
call bmi_initialize(trim(config_file))
end program test_df_bmi

compiled successfully via ifort so: ifort -o testbmifort bmi_fort-test.f90 -L/opt/dflowfm/lib/ -ldflowfm

Write % completed to log file?

2022-05-09T19:11:58Z

Is there a switch anywhere to get % completed written to the log file? The log file is full of lines like the following
** INFO : Solver converged in 16 iterations, res= 0.3395E-11 dt = 6.0000
which isn't really helpful, and what I'd really like to be able to do is look at the tail of the log file during a long model run and see how far along the job is. If that is not possible at this time, please consider this a feature request.

Issue in re-opening a project

2022-04-21T09:09:08Z

Hello everyone,

I have an issue when I re-open a previous DFM project.
Yesterday, I set up a simple 2d flow model and ran it. Everything seemed ok. The outputs were ok and correctly displayed into the GUI. I saved the project before exiting.
However, today, the project can't be re-open and raised a "critical error" box. Nothing is displayed apart from a big red cross. I attached the error message received.
It seems to concern the coordinate system projections but I don't really understand why...

If you can help me with it, I'll be very thankfull!

Many thanks in advance,
Rémi Caillibotte
