RAS Mapper: Index was out of range

[Niels Dedring]

Hello everyone,
I am new to HEC-RAS so I apologize for my lack of knowledge. Overall I want to simulate a glacial lake outburst flood in the Himalayas, but I already struggling at the beginning. After I loaded my DEM (12,5 x 12,5) into RAS Mapper everything seems normal. But after I reopened it the Legend of the Terrain shows some crazy Values and when I try to open its properties the following Error pops up:

Unhandled exception has occourred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediatley.
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging=”true” />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I hope someone can help me with this Issue.
Many Thanks in advance,
Niels

I would guess you have set up a 2D model with a breach in an embankment. Correct? How well does flow pass from upstream to downstream boundary conditions without the breach? Check elevations of the breach with regard to the terrain. If the breach goes lower than the terrain, the problem may be there.

[Niels Dedring]

Thanks for your response! I found my mistake and was much simpler… I haven’t changed the regional format of Windows from German to US, so HEC-RAS misinterpreted the , and .
