intro story Lake

Lake

Lakes and reservoirs are important resources for communities around the globe. They provide food, drinking and irrigation water and can also offer spots for recreation. Under certain conditions lakes can also represent a threat for local communities, such as flooding or limnic eruptions. The ecological state of shallow lakes may be hampered by suspended sediments due to wind driven currents and waves. In deep lakes, stratification can cause undesirable anoxic conditions in the deeper areas. Understanding these systems is crucial to enable a sound management of these water bodies.

 
Delft3D is the state-of-the-art modelling framework for hydrodynamics, water quality, ecology, waves and morphology.
 
Here, in this space, we share knowledge & experiences, and discuss issues related to modelling of lakes.

ABORT in FLOW2D3D: An exception occurred

Hi All,

Good day.

I am new user of Delft and am using it for my master's thesis for water quality.

It was my first time to run my simulation and I received the following error message:

*************************************************************************************************

Starting Delft3D-FLOW computation ...
--------------------------------------------------------------------------------
Deltares, FLOW2D3D Version 6.02.11.7184M, May 12 2017, 18:06:10

ABORT: error returned by tdatmain
Flow exited abnormally
ABORT in FLOW2D3D: An exception occurred

child process exited abnormally

*************************************************************************************************

I have been trying to find similar posts on this and haven't found one.

I have also checked the "TStops" of the *.mdf and *.dis files and have already equaled the values.

May you kindly assist me on how to solve the error?

Hi All,

In addition, I found the following file - td.diag<mdf filename> and has the following message:

I'll try to check/modify first the wind stress coefficients and update you on what happens after. emoticon
