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.

Compiling on windows 10 virtual machine: error during example

Hello everyone


First of all, thank you for taking the time.... This is my first post on the forum, i'm an undergraduate student and i'm trying to compile the Delft3D on windows.


Now to the point... im having issues with the compilation, ive already read a lot of the questions of the forum, it has been a lot of help ... i get the errors (flex.exe) and (byacc.exe), I was notified that flex.exe and byacc.exe was unable to start correctly, but for what ive read i can work without them, so the compilation created a bin folder and so far so good, by the way after these messages i have put my source folder with all permission option ...

the next step according to the Readme.file and the source code website is to run some examples, this is where i get stuck... in the first example
"run_flow2d3d.bat" i have the following message "d_hydro.exe - System error. The execution of the code cannot continue because cannot find libexpat.dll''.

The question here is how can i fix this ? im using the latest tag 7545.


My set-up: Visual Studio Professional 2015
Python 3.6.5. x86-64
Intel Parallel Studio XE 2016
Tortoise 1.9.7
Windows 10 (Virtual machine on a mac, 2.4 GHz Intel Core i5, 8 GB 1600 MHz DDR3)

oh and here is another question, is there any issue with running the software with a virtual machine? it seems that it has no problem so far..

I've attached the BuildLogs..

Hi Germán,

The errors in your build log are serious.

What version of Delft3D are you using? You should start with the latest tagged version, currently https://svn.oss.deltares.nl/repos/delft3d/tags/7545/

You are compiling in a directory with a white space in the path: "c:\program files\delft3d\delft3d_repository". Although this should not result in issues anymore, it's safer to compile in directory without white spaces in the path, e.g. "c:\sourcecode". And it's also good to avoid the "c:\program files" directory: Windows uses restricted permissions in there.

If you also create directory "c:\tmp", the lex/yacc errors will disapear too.

There are no issues related to running on Virtual Machines.

Regards,

Adri

Dear all, I have the same problems (all errors are similar) and I also use Windows on a MacBook but installed using BootCamp.

Windows 10;

Visual Studio 2015 update 3;

Intel Parallel Studio XE 2016 update 4 

My Delft 3D tag is 59659
