Specifies a user defined FLEXTRA executable. Both absolute and relative path can be given here. If it is left blank (this is the default) Metview will use the MV_FLEXTRA_EXE environment variable to locate the executable.
Specifies how the input data path is specified. The possible values are path and icon. When it is set to path we will specify the input data files and the AVAILABLE file by their paths. While in icon mode the input data is specified by a FLEXTRA Prepare icon in Flextra Input Data. The default value is path.
Specifies the location of the input data files using a FLEXTRA Prepare icon.
Specifies the FLEXTRA run label. The default value is: "FLEXTRA RUN".
Specifies the location of the input data files. Both an absolute and relative path can be given here. Enabled when Flextra Input Mode is path.
Specifies the location of the AVAILABLE file. The default is SAME_AS_INPUT_PATH, which means that the AVAILABLE file is located in the same directory as the input data. Enabled when Flextra Input Mode is path.
Specifies the run mode for the FLEXTRA simulation. The possible values are as follows:
The default value is normal.
Specifies the FLEXTRA simulation direction in time. The possible values are: forward and backward. The default value is forward.
Specifies the length of the FLEXTRA simulation. The format is HHH[:MM[:SS]
. The default value is: 48 (i.e. 48 hours).
Specifies the start date of the period within which the trajectories will be released. Enabled when Flextra Run Mode is set to normal or cet. The format is YYYYMMDD
. Relative dates are allowed: e.g. -1 means yesterday, 0 means today, etc.
Specifies the start time of the period within which the trajectories will be released. Enabled when Flextra Run Mode is set to normal or cet. The format is HH[:MM[:SS]
.
Specifies the end date of the period within which the trajectories will be released. Enabled when Flextra Run Mode is set to normal or cet. The format is YYYYMMDD
. Relative dates are allowed: e.g. -1 means yesterday, 0 means today, etc.
Specifies the end time of the period within which the trajectories will be released. Enabled when Flextra Run Mode is set to normal or cet. The format is HH[:MM[:SS]
