The Steady Flow Computational Options command of GeoHECRAS software allows the user to define steady flow computational options and tolerances. The software provides some default computational options and tolerances for 1D steady flow models. The tolerances are used in the solution of steady flow equations. In general, it is recommended that the default computation options and tolerances be maintained. However, the user can override the default computational options to achieve model stability while maintaining computational accuracy. Extra care should be taken while overriding the default calculation tolerances as it could result in computational errors in the water surface profile.
Follow the steps given below to use the Steady Flow Computational Options command:
The following sections describe how to interact with the above dialog box.
This section allows the user to select friction slope method, critical depth computation method, and conveyance method from various options.
This section allows the user to set values for various tolerances. These tolerances are used in the solution of the energy equation.
Note that increasing the default value for tolerances could result in computational errors in the water surface profile.
