The RiverSystem.CommandLine.exe provides a mechanism to run existing projects without the Source interface. It is possible to modify or change the behaviour of the project from the command line, by changing the values of global expressions. Results can be returned for recorded items or global expressions within the project.
RiverSystem.CommandLine.exe is included with Source.
The command line is used where it is impractical to run Source from the main user interface, such as:
- For batch runs, where Source is run many times with a range of different parameter values; or
- Optimisation scenarios; and
- When integrating Source with other models or business systems.
The command line can be used in either a standalone (in-process) mode or in a client/server configuration. When run in client/server mode, the Source project is loaded and run at the server side, with parameters provided by and results returned through the client. In this way, the server can be used for many runs of the same project, without needing to reload the project file each time.
Configuring a scenario from the command line
Any valid Source project can be used with the command line. To modify behaviour of the model, you must configure global expressions, which can be achieved using the command line.
Figure 1 illustrates the process of manipulating the operating target for a storage from the command line, in this case, manipulating a global expression, $x. This must first be specified in terms of an expression, which must reference $x. Global expressions can be used to manipulate the model in this way, either before the start of the simulation, or before each time-step.
Figure 1. Manipulating global expressions
The MetaParameter Explorer can be used to attach global expressions directly to model variables for situations where the Function Editor has not been enabled by default.
Working with the command line
This section describes how to load, run, retrieve results, and modify parameters using the command line.
| Info | ||
|---|---|---|

| Note: All characters in the command line are case-sensitive. |
Loading and running
You can run a project in the following modes:
- Standalone mode – the project loads; the simulation runs with a single line command:
| Code Block |
|---|
RiverSystem.CommandLine.exe -p C:\Temp\ExampleProject.rsproj |
- Client/server mode – one command line runs projects. It does anything except for loading a project until a second command line is run in client mode. In this way, multiple runs can be completed with the server loading the project only once. It also enables the server to run on a different machine to the client. The examples provided assume a client/server mode, illustrating the calls made by the client. They could also work in standalone mode. Refer to Advanced configuration options for two options available in this mode.
Retrieving results
By default, all recorded items are returned, as configured from within the Source application (Running scenarios). Alternatively, you can specify specific items to record by using a command line argument:
| Code Block |
|---|
RiverSystem.CommandLine.exe -m Client -r "Inflow 1/Inflow Volume" |
The command after -r refers to the exact name of the recordable item as it appears in Source, ie Node Name/Variable. In this case, the variable, Inflow Volume, of the inflow node will be recorded.
In client/server mode, results are always computed on the server, but returned through the client. By default, results are displayed on the console (in both standalone and client modes), but it is possible to save the results directly to a file using the following command (file name is resultsfilename.res.csv.):
| Code Block |
|---|
RiverSystem.CommandLine.exe -m Client -o resultsfilename.res.csv |
Modifying parameters
To modify parameters in the model, they need to be set up as functions. This can be done in one of three ways:
- Using the Function Manager directly;
- Creating a function and Adding function usages manually; or
- Using the Calibration Wizard. Refer to Working with metaparameters for more information.
| Info | ||
|---|---|---|
| ||
Note: When working with functions in the command line, ensure that functions are referenced by their full name to avoid errors or run failures. The syntax for referencing a function by its full name is $Folder.Function. For example, use: RiverSystem.CommandLine.exe -v "$Folder1.Function1=10" |
Use the -v argument to assign parameter values:
Set the values:
Code Block RiverSystem.CommandLine.exe -m Client -v "$metaParam=2.5"- Set multiple expressions:
| Code Block |
|---|
RiverSystem.CommandLine.exe -m Client -v "$metaParam=2.5" -v "$anotherMetaParam=3.0". |
Examples
The following set of examples indicate the type of commands used to run projects in the two modes.
Inprocess
The next example runs the project from start to finish and puts all recorded values in the file ‘test.csv’.

Server
This command starts a basic server on the same machine as the client:
| Code Block |
|---|
>RiverSystem.CommandLine.exe --mode server |
...
In this command, a basic server runs on the same machine as the client. This server will look for project files passed from the client in the directory "C:\ProjectDir":
| Code Block |
|---|
>RiverSystem.CommandLine.exe --mode server --d "C:\ProjectDir" |
...
The following command will start up a server, load a project from the directory C:\Users\man25n\Documents\eWater Source Projects using the address specified (net.tcp://192.168.1.5:8080/myWaterService/):
| Code Block |
|---|
>RiverSystem.CommandLine.exe --mode server -d "C:\Users\man25n\Documents\eWater Source Projects" -a "net.tcp://192.168.1.5:8080/myWaterService/" |
...
The address consists of the communication protocol (net.tcp) and the name of the end-point. For a machine that runs both the client and server, the address of the end-point must match.
Client
The following command assumes that the server is already running from the previous example:
| Code Block |
|---|
> RiverSystem.CommandLine.exe --mode client --d "C:\ProjectDir" |
...
Additional examples of running Source using a DOS batch file, a Python script or an R script can be found here.
...
In the client/server mode, there are two command line windows and RiverSystem.CommandLine.exe is run twice:
- XML file: RiverSystem.CommandLine.exe.config – This file contains a section called <system.serviceModel> that can configure hundreds of options for the services and client including transport types, maximum data size, security etc. These are the default options used when running in client or server mode. The location of the server defined in this file, by default, is "localhost" which means the server and client are configured to run on the same machine.
Option A - A project is loaded when the server starts (first command line) and is run in response to a client call (second command line):
| Code Block |
|---|
RiverSystem.CommandLine.exe -p C:\Temp\ExampleProject.rsproj -m Server
RiverSystem.CommandLine.exe -m Client |
- For testing purposes and ad-hoc configuration, two main command line options are also provided to configure the location/type of the server and message time out. When run in this mode the <system.serviceModel> section of the RiverSystem.CommandLine.exe.config file may need to be deleted as creating two servers of the same type is not supported. This means that the net.tcp server on localhost defined in the exe.config file will stop you creating an adhoc server of the same type.
Option B – In the example below, the server starts without loading any project (first command line). The client then specifies the project, which gets loaded onto the server and runs immediately (second command line):
| Code Block |
|---|
RiverSystem.CommandLine.exe -m Server
RiverSystem.CommandLine.exe -m Client -p C:\Temp\ExampleProject.rsproj |

Server
This command starts a basic server on the same machine as the client:
| Code Block |
|---|
>RiverSystem.CommandLine.exe --mode server |
The service is ready at net.tcp://localhost:8523/eWater/Services/RiverSystemService
Press Enter to stop the service.
In this command, a basic server runs on the same machine as the client. This server will look for project files passed from the client in the directory "C:\ProjectDir":
| Code Block |
|---|
>RiverSystem.CommandLine.exe --mode server --d "C:\ProjectDir" |
The service is ready at net.tcp://localhost:8523/eWater/Services/RiverSystemService
Press Enter to stop the service.
The following command will start up a server, load a project from the directory C:\Users\man25n\Documents\eWater Source Projects using the address specified (net.tcp://192.168.1.5:8080/myWaterService/):
| Code Block |
|---|
>RiverSystem.CommandLine.exe --mode server -d "C:\Users\man25n\Documents\eWater Source Projects" -a "net.tcp://192.168.1.5:8080/myWaterService/" |
Press Enter to stop the service.
The address consists of the communication protocol (net.tcp) and the name of the end-point. For a machine that runs both the client and server, the address of the end-point must match.
Client
The following command assumes that the server is already running from the previous example:
| Code Block |
|---|
> RiverSystem.CommandLine.exe --mode client --d "C:\ProjectDir" |
The service is ready at net.tcp://localhost:8523/eWater/Services/RiverSystemService.
Additional examples of running Source using a DOS batch file, a Python script or an R script can be found here.
Client Server interaction
The service will keep the current state after the client command completes. Projects that are loaded, steps executed and parameters set are still in effect on the server until changed. The client can change this by loading another project or changing state in some other way. This allows for very complicated interactions.
A simple situation is to load a project and run it multiple times with changing values. This would be accomplished by first starting a server
| Code Block |
|---|
> RiverSystem.CommandLine.exe -mode server |
Then loading the project in the server from the client in another window while the server is running.
| Code Block |
|---|
> RiverSystem.CommandLine.exe -mode client -p c:\test.rsproj -s 0 |
NOTE: the "-s 0" in the command above will stop the project from running by default. The project will load and wait, not performing any timesteps ("-s 0")
Next we set some parameter on the loaded project
| Code Block |
|---|
> RiverSystem.CommandLine.exe -mode client -v "$metaParam=2.5" -s 0 |
Then run the project (running is the default action of the commandline so no extra paramaters need to be specified)
| Code Block |
|---|
> RiverSystem.CommandLine.exe -mode client |
Executing the project again with a different value for the parameter can be performed as follows.
| Code Block |
|---|
> RiverSystem.CommandLine.exe -mode client -v "$metaParam=7.5" -s 0
> RiverSystem.CommandLine.exe -mode client |
OR just
| Code Block |
|---|
> RiverSystem.CommandLine.exe -mode client -v "$metaParam=7.5" |
which will set the parmeter and execute the model (the default operation because no "-s 0" is present to stop the execution)

The location of the server defined in this file, by default, is "localhost" which means the server and client are configured to run on the same machine.
Option A - A project is loaded when the server starts (first command line) and is run in response to a client call (second command line):
| Code Block |
|---|
RiverSystem.CommandLine.exe -p C:\Temp\ExampleProject.rsproj -m Server
RiverSystem.CommandLine.exe -m Client |
- For testing purposes and ad-hoc configuration, two main command line options are also provided to configure the location/type of the server and message time out. When run in this mode the <system.serviceModel> section of the RiverSystem.CommandLine.exe.config file may need to be deleted as creating two servers of the same type is not supported. This means that the net.tcp server on localhost defined in the exe.config file will stop you creating an adhoc server of the same type.
Option B – In the example below, the server starts without loading any project (first command line). The client then specifies the project, which gets loaded onto the server and runs immediately (second command line):
| Code Block |
|---|
RiverSystem.CommandLine.exe -m Server
RiverSystem.CommandLine.exe -m Client -p C:\Temp\ExampleProject.rsproj |
