HPC Model Review: Difference between revisions

If bouncing or an unusually low timestep is observed in the HPC dt time series it is important to also review the value associated with for each control number (Nu, Nc and Nd). This will allow the modeller to determine which hydraulic condition is limiting the timestep most. In the example below, the Wave Celerity condition is reducing the timestep as shown by the highlighted Nc value of 0.999.<br>

 

 

This becomes valuable when trying to determine what is causing the low timestep and how to resolve it. For example:<br>
