= HPC TUFLOW Log File (*hpc.tlf) =

The.hpc.tlf log file records “repeated timestep” if there is a significant change in timestep. It is inevitable to have repeated timesteps, if a model has a sudden change in rainfall input from one timestep to the next, or has a warmup period with small flow rate before a large inflow. However, if there is a high occurrence of repeated timesteps when the boundary inflows are smooth, this could be an indicator of model instability.<br>

 

The new *hpc.tlf file can be also used to review the dt, controlling number values and the water volume in the model. However, this may be easier to review using the hpc.dt.csv output.<br>
