Delft3D FM Open Source Community The worldwide open source release is scheduled for 2021.   For now, as (1) the 1D-2D-3D architecture is still subject to change and (2) we have to focus our...

Coupled FLOW and WAVE

Hei!For my project work in the university, I need to couple the Flow-FM and the Wave Module. Both of the models are running stand-alone without any problems. After putting them into the...

Writing groundwater_out variable to the output *_map.nc file

Hi.With the new Delft FM, one can simulate groundwater infiltration process, which is great. But the amount of water lost to groundwater is not written onto the *_map.nc file. I also notices that...

RE: vertical layers

Please use a more recent version of the D-Flow Flexible Mesh user manual. Then, in Chapter 10 ( "3D Modelling") you can find how to specify layer thicknesses. See keyword StretchCoef.

RE: positive and negative values below reference plane

Hi Marina, I don't know the exact reason for this. My guess is that D-Waves can handle only structured grids (recti- or curvilinear), which where initially used by Delft3D-FLOW and Delt3D-WAVE...

vertical layers

Hey guys,I'm new in Delft3D-FM for my studies at university. I'm simulating some waves and flow through the wind in a lake. So I should put vertical layers to get more realistic values for...

RE: positive and negative values below reference plane

Thanks Dmitry,do you know the reason for that?And if I want to couple them and I say I want to use the Bed level from Flow, is the program converting the values by itself, or can't I use the...

RE: positive and negative values below reference plane

Hi Marina, That's right. In D-Flow FM (unstructured grids), the sign convention for bathymetry is positive upwards. In D-Waves (curvilinear grids) depth is positive downward. Regards, Dmytro

RE: positive and negative values below reference plane

Hei Sebastian, thanks for your response, but in the manual is written:Flow: 5.4.4 Bed levelWhen you double click on Bed level in the Project window or select Bed level from the dropdown box in the...

RE: Issue with Rainfall Specification with new .ext file

Hi Sebastian,The problem was with the initial water levels as you pointed out. Thank you very much!I wish you a nice week ahead.Cheers,Veethahavya.

RE: Issue with Rainfall Specification with new .ext file

Hi Veethahavya,To be honest with you, I’ve never done a simulation including rainfall.Looking at your .mdu file, I see that the only external forcing is rainfall. Is this correct?Regarding the...

RE: Issue with Rainfall Specification with new .ext file

Hi Sebastian,Thank you very much. That solved the issue. However now I have another problem that I do not understand and would be grateful for any help/insight.As you may see in the screen snips, I...

RE: Issue with Rainfall Specification with new .ext file

Veethahavya,Check your .mdu file, Tzone should be in the range (-12 +12).Regards,Sebastian

Issue with Rainfall Specification with new .ext file

Hi.I am using the CLI of D-Flow FM version 1.2.105.67514M.I want to simulate rainfall over the whole model area with time series data so I tried using the new external enforcing file with a .bc...

Storm Surge Model showing abrupt result! How to set Initial Conds and BC?

Hi, I am trying to set up a coastal flooding model using Delft3D FM for Hurricane Florence, NC, USA. However, the model without wind and pressure fields shows tidal water level liitle bit...

RE: positive and negative values below reference plane

Hi Marina!In Delft3D-FM all levels are measured with a positive vertical axis "pointing up", i.e. oposed to the vector "g" (gravity).Hope it helps.Sebastian

positive and negative values below reference plane

Hi everyone,I'm using Delft3d-FM for a university project and during studying the Manuels for Flow and Wave I recognized a discrepancy. Flow is measuring the bed below the reference plane as...

RE: How to deal with islands?

Hi everybody,is there anything new to say about this issue? It has been almost a year since the thread creation without answer.Thank you very much,David
