Hi All,
I am trying to run an historic HecRas Model (V2.2) I think and am having a problem at Steady Flow Runtime (Using V5.0.1 64 bit).
When I press compute it seems to run ok (looking at the log file) until it gets to a particular culvert section.
This is the only message displayed:
‘Span of 11.811 is less than minimum span of 20.083
C_ARCH_F’
The 11.811 is the 3.6m span in ft, and the 20.083 is 6.121m in ft. Looking at the culvert details it is a High Arch, set to 3.6m span (hence how I know it is this section). It is stated:
‘High Arch properties interpolated from 0 to 6.121(m)’
My question are:
1. Is this an error with the model, or a change in naming from V2.2, as this has been supplied to me as a working model?
2. Has anyone got an idea how to get around the issue?
Regards,
Ben
