SimTunnel Pro vs Open Channel Flow Lite

SimTunnel Pro is designed to perform a quick tunnel analysis on your phone device. SimTunnel Pro is very simple and easy to use. SimTunnel Pro uses "rock-support interaction" or "convergence-confinement" method to estimate the deformation of circular tunnels in weak rock, and visualizing the tunnel interaction with various support systems. SimTunnel Pro has the following features: - SimTunnel Pro determines Factor of Safety (FOS) as the ratio of maximum support pressure to the support pressure required for equilibrium. - The Tunnel and Rock Parameters dialog allows you to define the tunnel and rock properties for model. - The Strength Properties which are required will depend on the strength criteria you have selected in Setting Page. - Both Mohr-Coulomb and Hoek-Brown strength criteria are available. - The parameter calculator dialogs are available to help you to calculate some of the parameters (i.e. GSI, mi, D, UCS, insitu stress and etc). - The support parameters dialog allows you to easily add support and define the support properties for the model. - Three different support types can be added to the model: Rockbolts, Steelsets and Shotcrete - The ground reaction curve (GRC) is always displayed in the output page. - The brief summary of analysis results and input data will be displayed in the Output Page. - The report button, allows you to save the current model’s input and output information into PDF file. The generated report file can be sent out via email.

Open Channel Flow Lite is the free edition of Open Channel Flow Pro. It has every feature of the Pro version, for small channels. CHANNEL SHAPES • Rectangular • Trapezoidal • Circular • Natural (irregular cross-section, with overbank roughness) • Triangular • Parabolic SOLVE FOR • Discharge, water depth, bed slope, and the channel width or pipe diameter, using Manning's equation RESULTS • Flow area, wetted perimeter, hydraulic radius, velocity, Froude number and flow regime • Critical depth, specific energy, alternate and sequent depths • Discharge rating curve and specific energy charts MORE TOOLS • Water surface profiles by the direct step method, from a control depth • Efficient Section: size the best section for a design discharge • Manning's n picker • Metric and English units • Worksheets to save and reopen your calculations • PDF reports to share • Built-in documentation and usage manual • iPhone and iPad LIMITS OF THE LITE VERSION • Discharge up to 0.5 m³/s (17.65 ft³/s) • Water depth in a circular channel up to 0.6 m (1.96 ft) • Trapezoidal side slope of 1:1 only Open Channel Flow Pro removes these limits.
