intro story Coast / Estuary

Coast / Estuary

Coastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. 
 
Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter).
Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind- or wave-induced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting. 
 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

offline wave computation won't start

Youngling Posts: 6 Join Date: 6/24/11 Recent Posts
Dear Support,

I'm trying to start a wave computation with input from a flow-computation which I've already executed, so it's an offline coupling. Both the mdf and mdw have the same name. However, the delft3d-prompt gives the following error:

*** ERROR: Delftio initialization WAVE side failed
Is file 'dioconfig.ini' present?

The dio-wave-error file gives the following:

DioError 101: Could not connect to stream FLOW2WAVE_DATA.his
DioError 203: Could not open FLOW2WAVE_DATA for reading

I've already copied the dioconfig.ini from the w32/wave/default-folder into the working-directory, but this has no effect. I've also tried this with the dioconfig.ini from svn.oss.deltares.nl, but to no effect.

What can I do?

Hi Menno,
Does it run when you do not use information from FLOW?
If so, are you 'reference dates' in both FLOW (so in the com-file) and WAVE identical?

Cheers, Arjen

Hi Arjen,

When WAVE is run in standalone-mode, so with manual input in the 'Time Frame' window, it runs without problems. In both cases, the same reference date is used.

FYI: an online FLOW-WAVE computation has no problem starting. It's purely the offline WAVE simulation with input from a com-file that causes trouble.

Hi Menno,

I am also facing the same problem when running a coupled flow-wave simulation. Could you able to solve this error. I was running flow-wave coupled simulation, but now it shows this error" *** ERROR: Delftio initialization WAVE side failed Is file 'dioconfig.ini' present? " but this is present in the folder and dio-wave-errors shows" DioError 101: Could not connect to stream FLOW2WAVE_DATA.txt DioError 903: Could not open FLOW2WAVE_DATA.txt for deletion.

Looking for anyone's help to solve this problem

Regards,

RE: offline wave computation won't start (Answer)

Hi Glejin

I have observed a similar sequence of error messages (although I've never managed to establish the cause).

The approach I adopt is to deal with this is
1) ensure that all output files are deleted from the simulation folder
2) first delete the dioconfig.ini file then copy a fresh version of it to the simulation folder

If the error messages remain I create a new simulation folder and repopulate it with the input files and dioconfig.ini.
So far this approach has cleared the issue.

I've tried every different permutation of this, and still have the problem. Does anyone have a solution to this?

Hi.

Did you edit the mdw to write the timesteps to solve? It should look something like this:

[WaveFileInformation]
FileVersion = 02.00
[General]
ProjectName = Meranti
ProjectNr = 001
Description = 2016 11 14
Description = Wave only
OnlyInputVerify = false
SimMode = stationary
FlowWaterLevel = 1
FlowVelocity = 1
FlowVelocityType = depth-averaged
DirConvention = nautical
ReferenceDate = 2016-09-10
MeteoFile = Meranti-JMA-micro.spw
[TimePoint]
Time = 4.6800000e+003
[TimePoint]
Time = 4.6900000e+003
[TimePoint]
Time = 4.7000000e+003
[TimePoint]
Time = 4.7100000e+003
[TimePoint]
Time = 4.7200000e+003
[TimePoint]
Time = 4.7300000e+003
[TimePoint]
Time = 4.7400000e+003
[TimePoint]
Time = 4.7500000e+003
[TimePoint]
Time = 4.7600000e+003
[TimePoint]
Time = 4.7700000e+003

...

[TimePoint]
Time = 5.7600000e+003
[Constants]
WaterLevelCorrection = 0.0000000e+000
Gravity = 9.8100004e+000
WaterDensity = 1.0300000e+003
NorthDir = 9.0000000e+001
MinimumDepth = 5.0000001e-002

...




And to reiterate the importance of what other responders already said, make sure that you delete the comm files first before re-running.

Hope this helps.


Sincerely,
Marjorie

I had a similar issue if I was running a batch of simulations. I discovered that if my computer had gone into sleep mode then the communication between the flow and wave modules had some sort of glitch and I would get this error. When I changed my computer settings I stopped having this issue.

I don't know if your problem still exists after 6 years but since this is the first result on Google and I have searched so hard for a solution to this problem, I wanted to reply my solution. So:
1) I have gone to the directory where Delft3D was installed. In my case it was located in D:\Program Files (x86)\Delft3D. 2) I have searched for dioconfig.ini in that directory. Windows explorer found 3 of them.3) I have opened the files one by one and changed the following lines:[Settings]
#Use delay=500, sleeptime=20 when delftio is used for synchronising, while data transfer is done via files
#Delay=500
#SleepTime=20
# timeOut in communication DD;UU;MM;SS.S/100
TimeOut=00;10:00:00.00
to:[Settings]
#Use delay=500, sleeptime=20 when delftio is used for synchronising, while data transfer is done via files
Delay=500
SleepTime=20
# timeOut in communication DD;UU;MM;SS.S/100
TimeOut=00;10:00:00.00
So basically I have removed number signs (#) in front of Delay and SleepTime. This solved my problem. Also, if this solution does not work, you can try increasing Delay as one forum member mentioned in the following link:https://oss.deltares.nl/web/delft3d/lake1/-/message_boards/message/1192481
Also, another user mentions that disabling Kaspersky is another solution as stated here:https://oss.deltares.nl/web/delft3d/river1/-/message_boards/message/1245723
But I haven't tried either of them since removing the number signs solved my problem. Also, I really don't know if this solution is harmful for the system. So please apply it on your own risk.Sincerely,Arda

Dear Arda,
thank you very much for your effort looking for a solution for this issue.
It has worked for me right away.
Best,
