Re: Calculation of Geostrophic Current

Dear all,

actually, I had a similar question last week and I'm quite happy there is some discussion about that.
However, as this is really a basic issue of physical oceanography, I assume there are other posts concerning this topic, which I might have missed.

My comment is more a fundamental one ...

Re: ROMS tidal forcing with water elevation ONLY

Dear all,

we saw also this behaviour of blowing-ups when only using tidal boundary conditions and reduced 2d momentum conditions.

Usually, I use a dirty trick to reduce the instabilities. It is a kind of damping, which was also introduced into FVCOM to stabilize the model at open boundaries.

It ...

two-way nesting with wet-dry treatment

Dear all,

I hope I did not miss the answer to the following question inside the forum.

We are using two-way nesting for tidal-flat applications.

When comparing the free surface in coarse and fine grid within the same region, one can see a difference in dry areas. Whereas in fine grid, zeta meets ...

Re: ROMS-SWAN coupling, nearshore_MELLOR08 : Segmentation fa

Dear all,

in the meantime I checked this issue on another computer platform with a newer version of the intel fortan compiler.

Using the compiler version:
Intel(R) Fortran Compiler XE for applications running on IA-32, Version 12.1.4.319 Build 20120410

The segmenttion fault does not appear any ...

Re: ROMS-SWAN coupling, nearshore_MELLOR08 : Segmentation fa

Dear John Warner,

thanks very much for your answer and offer.
I really would like to check the COAWST code as well.

In the meantime, I found a quick solution to the original problem which is working but is still quite strange.

The source of the error seems to come from several lines above when ...

ROMS-SWAN coupling, nearshore_MELLOR08 : Segmentation fault

Dear all,

I started using the ROMS-SWAN coupling with the inlet test case.
I could successfully compile and run the model with the nearshore_MELLOR05 option.

Then I changed to the NEARSHORE_MELLOR08 option for calculating the radiation stresses.

When running the model on 2CPU's I got a ...
