|message_desc=TheHPC initialuses timestepa forminimum theallowable HPCand Solvera mustmaximum beallowable greatertimestep thanin the minimum permissibleadaptive timestep calculation. The initial
supplied timestep must be within these limits. When the timestep is being increased it will be limited to the defined
maximum timestep. When the timestep is being decreased, the model will be declared unstable if it falls below the
minimum timestep.<br>
Note that:<br>
* The initial timestep passed to HPC is 1/10th of the timestep defined in the tcf.
* The default minimum timestep is the lesser of 0.1s and cell size divided by 200 m/s.
* The default maximum timestep is the cell size divided by sqrt(gh) where h is the wet/dry threshold.
 
|suggestions=
* Ensure that the minimum timestep (if defined) is 1/10th or less of the initial timestep.
The minimum permissible target timestep allowed for the HPC Solver is set with the 'Timestep Minimum' TCF command, where the default is the minimum of 0.1 seconds or the cell size divided by 200 m/s. This value must be less than the initial timestep value specified for the HPC Solver with the 'Timestep' or 'Timestep Intitial' TCF commands. The timestep can also not be less than 0.000001s.
* Ensure that the maximum timestep (if defined) is greater than the minimum timestep.
