error = Index was out of range

[Anonymous]

Just trying to figure out how to solve the below error that comes up when I try to complete steady flow analysis. Any help would be appreciated.

“Writing Geometry
Computing XS Interpolation Surfaces
Error generating interpolation surface
Error creating TIN for region between XS’s:
River: Lucky Creek Reach: Reach 1 River Station: 530
River: Lucky Creek Reach: Reach 1 River Station: 510
error = Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index”

Cheers!

Do the cross-sections overlap or is there a big difference between how wide the cross-sections are at that location?

Hey Luke,

Did you get the issue solved? I got the exactly the same error messages

It’s likely your working folder has previous files and that probably the reason to cause the problem.

Clear the working folder first and re-generate the RAS files, it will solve the problem.

Thanks,

set bank stations to 10-year and re-run, it should resolve the issue.
