			\|message_desc=When running in adaptive timestep mode (the default) HPC will monitor the the courant, celerity, and peclet (diffusion) control numbers on a timestep by timestep basis.
	\|message_desc=In the HPC solver, the timestep is adjusted if it breaches the mathematical stability criteria of a 2D SWE explicit solution. The timestep is allowed to be adjusted less than 10 times in each simulation steps by default, and this number is not allowed to be change at the moment.
			At the end of a timestep, if NaNs are encountered in the solution, or any of the three control numbers has jumped to more than 20% above their control targets, the step results are

			invalidated and the step repeated with a reduced timestep. Normally the solution is then able to progress stably again. However, consecutive repeat timesteps indicate a
			severe discontinuity at that point. HPC will abandon the solution if the number of consecutive repeat timesteps exceeds a threshold limit.
			The default limit is 10, but is able to be adjusted with the "<font color="blue"><tt>Timestep Repeats</tt></font>" tcf command.

			\|suggestions=Generally, changing the timesteps repeats limit is not the best method to solve the problem.
			For models that remain dry for a period of time before receiving a sudden inflow, the model timestep may increase during the dry period requiring a number of
			consecutive repeat timesteps at the onset of inflow in order to return the timestep to a more typical value. In this case, use the "<font color="blue"><tt>Timestep Maximum</tt></font>" tcf command to limit the model
			timestep during the dry period and hence the number of consectutive repeat timesteps at the onset of inflow.
			For models that are encountering instabilities, these can sometimes be solved using the "<font color="blue"><tt>Control Number Factor</tt></font>" tcf command to force the adaptive timestep control to use smaller timesteps.
			Otherwise, the user will have to troubleshoot the source of the instability through the checkfiles.
