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.

Delft3D Flow: Meteo files: spherical (curvilinear) grid crashing

Hi all,

I'm having a very frustrating time trying to get space varying wind and pressure input (meteo files) working when using a spherical grid (Filetype = meteo_on_curvilinear_grid). This is what happens when I try:

Some notes/things I have tried:
I've combed over the meteo files and can't find any errors (attached)
I get the same error when using GNU or intel compilers
I have tried multiple different tags besides the one above (
I have compiled on both a stand-alone Linux box (Ubuntu 16.04) and a Dell PowerEdge M630 cluster system running Linux - and get the same errors.
The compiled code runs all the examples and a test using 'meteo_on_equidistant_grid'
The study area is in the southern hemisphere - does this matter?

I am hoping someone has some insight before I go wading into the code - I'm a pretty poor fortran programmer!

Very appreciative if anyone has any input!
