Atmospheric pressure entry created by GUI is not accepted by dflowfm

Hello,

Since there is no other tool for formal reporting bugs I am posting here one.

Uniform pressure time series is not accepted by dflowfm 1.1.171 ( in Linux). With previous GUI versions adding the time series was not even possible.

Snapshot of the error during startup:
------------------------------------------------------------
** INFO   : Done initializing flow model geometry.
** INFO   : Start initializing external forcings...
** INFO   : External Forcing or Initialising 'windxy' from file 'meteoeng.wnd'.
** INFO   : External Forcing or Initialising 'atmosphericpressure' from file 'atmosphericpressure.tim'.
** FATAL  : m_meteo::ec_addtimespacerelation: Unsupported filetype for quantity wind_p.
** INFO   : Closed file : Toronto_Harbour_Water_Level_FM_Model.ext


Procedure to introduce it in the model :
----------------------------------------------------------
The extension file for the meteorological conditions was created in Deltashell 1.1.2 by adding
1. in the Model tree -> Physical parameters -> Wind (right click)
2. select * Air pressure time series -> Uniform pressure (right click) -> import time series

See the resulting atmospheric pressure time series in the attached GUI snapshot.

The extension file: Toronto_Harbour_Water_Level_FM_Model.ext
----------------------------------
QUANTITY=windxy
FILENAME=meteoeng-hourly-08012013-08312013.csv.wnd

Dear Bogdan,

Sorry for the inconvenience but indeed DflowFm core code did not support the Uniform pressure field. We have included this functionality in the current trunk version and I believe these changes will be included in an upcoming release.
Could you please elaborate for what purpose you require this functionality. Based on our experience this should not influence your simulation.
In the current released version we support air pressure on grid option (concerning pressure).

Kind regards,
Michal

Hear Michal,

Given that the pressure is uniform, indeed I believe that it should not influence the simulation. I used that option as I saw that it was available in DeltaShell and with the hope that later I can change to a grid if I can get the data. On a second thought, I was trying to see if the air pressure would affect the water level oscillation in certain narrow slips.

Kind regards,
Bogdan
