FAST
FAST is a two-dimensional model for tsunami calculations.
FAST Module Adapter
This page describes the FAST module adapter, its functions, and provides an example for configuring a FAST run in FEWS.
It only has a pre adapter since FAST generates output that is already readable by FEWS.
FAST pre-adapter
Model pre-adapter for running a FAST model from Delft-FEWS.
Class name: nl.deltares.fast.FastPreAdapter
Notes for users
- For all files that are written by this adapter, if the file to be written already exists, then it will be overwritten.
- This program writes log messages to a log file called Fast_Pre_Adapter.log.
- This program uses the information in the specified netcdf run file as input and uses this information to do the following:
- Replace the tag $WAVE_HEIGHT$ in template file (cil0_30mv3_TEMPLATE.xyz) with a wave height value from FEWS.
System requirements
- This program needs Java version 1.7 or higher.
- This program needs the following Java libraries:
- castor-0.9.5.jar
- commons-httpclient-3.0.1.jar
- Delft_Util.jar
- fews-FAST-adapter.jar
- log4j-1.2.14.jar
- netcdf-4.2.jar
- slf4j-api-1.5.6.jar
- slf4j-log4j12-1.5.6.jar
- xercesImpl.jar
Example configuration
A complete example model run configuration file can be found here: FastAdapterRun.xml
Start up activities
As a first activity it can be useful to delete all files present in the workDir, if for example it would be filled with files from a previous run.
<startUpActivities> <purgeActivity> <filter>workDir*</filter> </purgeActivity> </startUpActivities>
Export activities
The first steps in the general adapter run are the data set, netcdf and run file export activities. The <exportDataSetActivity> will extract a zip file with the module instance id as file name located in "Config\ModuleDataSetFiles\" of the FEWS environment to the workdir. The <exportNetcdfActivity> will be a netcdf file which can have any name containing a variable called wave_height which has exactly one value. The <exportNetcdfRunFileActivity> will be a netcdf run file that contains information needed by the pre adapter. The information will be automatically filled by the general adapter.
<exportActivities> <exportDataSetActivity> <moduleInstanceId>Run_FAST</moduleInstanceId> </exportDataSetActivity> <exportNetcdfActivity> <exportFile>wave_height.nc</exportFile> <timeSeriesSets> <timeSeriesSet> <moduleInstanceId>Run_FAST</moduleInstanceId> <valueType>scalar</valueType> <parameterId>WaveHeight</parameterId> <locationId>Dummy</locationId> <timeSeriesType>external historical</timeSeriesType> <timeStep unit="hour"/> <relativeViewPeriod unit="hour" start="0" end="0"/> <readWriteMode>add originals</readWriteMode> </timeSeriesSet> </timeSeriesSets> </exportNetcdfActivity> <exportNetcdfRunFileActivity> <description>This run file is passed as argument to FastPreAdapter</description> <exportFile>run.nc</exportFile> </exportNetcdfRunFileActivity> </exportActivities>
Execute activities
The next steps are the execute activities.
The first will be the pre adapter. This program will read the run.nc input file and use the contents for instructions on which directory and files should be used to convert to the correct FAST input format. The Pre adapter generates a log file called fast_pre_adapter.log, which can be read into FEWS by coupling line patterns to FEWS log messages.
The second execute activity will be the module run.

Wave spectrum conversion
"bcfile.nc" will be used to write the wave spectra into the following format:
- bcfile.txt referencing to wave spectrum files and a time of how long these should be used in each calculation step
FILELIST 3600.0 1.0 bc.time001.sp2 3600.0 1.0 bc.time002.sp2 3600.0 1.0 bc.time003.sp2 3600.0 1.0 bc.time004.sp2 3600.0 1.0 bc.time005.sp2 3600.0 1.0 bc.time006.sp2 3600.0 1.0 bc.time007.sp2 3600.0 1.0 bc.time008.sp2 3600.0 1.0 bc.time009.sp2 3600.0 1.0 bc.time010.sp2
- bc.time001.sp2 containing a wave spectrum

Water level conversion
In this example "zs0file.nc" will be used to write the time dependent water levels to a file named "zs0file.txt". The first column specifies the time (meaning defined in "PARAM_TUNITS") and the second column water level. For now the adapter only supports the water level as a single boundary condition but FAST has to possibility to also use 2 or 4 resulting in 1 or 3 extra columns.

Parameter conversion
It is possible to change model parameters as defined in params.txt from FEWS. The pre adapter will convert all run file properties starting with "PARAM_" to FAST parameters in "params.txt". Example: params.txt.
It reads the existing "params.txt" and searches for a line starting with the specified parameter and replaces the whole line with "parameter = value" or adds a new line in the same format when the parameter was not present yet.

Executing model run
The next activity will be executing the FAST model run. This is done by running FAST.exe in the workdir containing the model files.
<executeActivity> <command> <executable>FAST.exe</executable> </command> <timeOut>99999999</timeOut> </executeActivity>
Importing FAST output
The last part of the general adapter run is importing the FAST output. xboutput.nc contains all parameter, output and grid information of the run. This can be visualized in FEWS after defining the needed parameters, location and grid. How to do this can be found here: FAST FEWS setup
