open TELEMAC-MASCARET The mathematically superior suite of solvers

Also I wrote the atmospheric parameters and checked, it is correctly read.

Did you add AIR PRESSURE = YES in your steering file?

If I use AIR PRESSURE = yes

I am getting following error.

And if you don't use it, the pressure is not take in account...
Looks like a problem of recognition of pressure in your file.
You should investigate

For the influence of wind, did you try to play with the COEFFICIENT OF WIND INFLUENCE ?
The parametric formulation may not be dedicated to represent hurricane events where strong winds occur. The values mentioned in the manual for wind higher than 19.22m/s may be underestimated during this kind of events. Maybe you can try higher values to see if you can better fit with your comparison data (other model results or in-situ measurements will be better if available).

For the air pressure, first check that the name of the pressure variable in your atmospheric data file is PRESSURE.

Hello

To continue with recommendations of Laurent and Christophe:
- subroutine meteo.f is used for reading, interpolating and prescribing the atmospheric inputs. Add it to your fortran file and check with some WRITE(LU,*) is your interpolation of winnd and aire pressure is correctly done or not
- there is several unconsistancies in your steering file:

IMPLICITATION FOR DIFFUSION OF VELOCITY =0.5 ==> use rather 1.
H CLIPPING =true ==> use False
IMPLICITATION FOR DEPTH =3 ==> 1. is the highest value
SPATIAL PROJECTION TYPE = 2 ==> This means that coordinates are already transformed to Mercator projection, is it your case? or you are using longitude Latitude?
OPTION FOR WIND =3 ==> This means that you have to edit subroutine meteo.f but I see that keyword FORTRAN FILE is commented, which means that nothing is taken into account properly. See example wind_txy which gives you the way to proceed in your case.

I hope this helps

with my best regards

Hi
I did all modifications. Its working. Now a different problem. The tide effect is totally diminished in the results.

Hi

Herewith I am attaching the updated cas file.


Thank you

Hi all
I found what was the problem. meteo.f modifies the bottom topography.
why?
So only if the bathymetry is modified wind effect is seen. If bathymetry is kept the same, then there is no wind effect.

I was able to make changes in including air pressure and all suggested changes but the cyclonic effect on current speed and surface elevation is seen only if bottom topography is modified.

So is it possible to get better result if I opt no friction condition?

Hi,

The meteo.f subroutine does not modify the bathymetry, it's not possible except if you change the variable ZF inside...
The only modification of the bathymetry I see is the 10 smoothings of the bottom you ask in your steering file, which is independent of the meteo.f subroutine.
What are the modifications you did in meteo.f ?

Can we see time series of surface elevation and current speed for a point of your domain without and with wind influence please ? along with time series of wind (and pressure) at the same point.

Regards,
Laurent
