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.

start up activities
		<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.

export activities
		<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.

execute activities
		<executeActivities>
                        <executeActivity>
				<command>
					<className>nl.deltares.fast.FastPreAdapter</className>
					<binDir>adapter\bin</binDir>
				</command>
				<arguments>
					<argument>run.nc</argument>
				</arguments>
				<logFile>
					<file>d:\Data\FEWS_Issues\FEWS-11415_FAST_adapter\workDir\Fast_Pre_Adapter.log</file>
					<errorLinePattern>ERROR*</errorLinePattern>
					<warningLinePattern>WARN*</warningLinePattern>
					<infoLinePattern>INFO*</infoLinePattern>
					<debugLinePattern>DEBUG*</debugLinePattern>
				</logFile>
				<timeOut>99999999</timeOut>
				<ignoreDiagnostics>true</ignoreDiagnostics>
			</executeActivity>
		</executeActivities>

Wave height input file

Th exported netcdf file with the wave height will be used to write the wave height to cil0_30mv3.xyz by replacing the tag &WAVE_HEIGHT& in cil0_30mv3_TEMPLATE.xyz:

cil0_30mv3_TEMPLATE.xyz
108.34958333  -7.83289859   $WAVE_HEIGHT$    900 1
108.35411600  -7.83289136   $WAVE_HEIGHT$    900 1

108.38745431  -7.82846972   5.00    900 1

Executing model run

The next activity will be executing the FAST model run. This is done by running FASTrun.exe in the workdir containing the model files with the input file names as arguments.

module run execute activity
			
			<executeActivity>
				<command>
					<executable>FASTrun.exe</executable>
				</command>
				<arguments>
					<argument>cil0b2</argument>
					<argument>cil0_30mv3</argument>
				</arguments>
				<timeOut>99999999</timeOut>
				<ignoreDiagnostics>true</ignoreDiagnostics>
			</executeActivity>

Importing FAST output

The last part of the general adapter run is importing the FAST output. cil0_30mv3_out.asc contains the output in grid format of the run.

model run output import activity
		<importActivities>
			<importCustomFormatTimeSeriesActivity>
				<importFile>cil0_30mv3_out.asc</importFile>
				<parserClassName>nl.wldelft.fews.pi.EsriAsciiGridParser</parserClassName>
				<timeSeriesSets>
					<timeSeriesSet>
						<moduleInstanceId>Run_XBeach</moduleInstanceId>
						<valueType>grid</valueType>
						<parameterId>H_mean</parameterId>
						<locationId>Fast</locationId>
						<timeSeriesType>external historical</timeSeriesType>
						<timeStep unit="nonequidistant"/>
						<readWriteMode>read complete forecast</readWriteMode>
