Acceptable level of error in the Volume Conservation

[Robert]

Hello,

I was checking my result´s model (only 2D flow) using View Computation Log File and my percent error is 0.01266 % (see URL: http://1drv.ms/1Xdilp7)

Could you advise me, if guidelines of HEC-RAS define the acceptable error in the Volume Conservation?

For example:
Guidelines of Flo-2D recommend to keep an error of volume conservation under value 0.001 %.

thank´s for your reply
regards

Anecdotally, I have heard that a percent error less than 1% is ideal. Also, percent errors from 2-3% supposedly can be okay for rain on mesh. Looks like your percent is reasonable.
