Description
The initial timestep for the HPC Solver must be greater than the minimum permissible timestep.

Suggestions
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.
