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.

Whilst it is possible to increase the default HPC Courant, shallow wave celerity and diffusion control numbers (effectively overclocking the simulation), it is strongly recommended not to increase the Control Number Factor above the default of 1.0.

TUFLOW Message
ERROR 3011: Target control number must be in range 0.001 - 1.2.

Alternate Message
None

Message Type
ERROR

Description
This error message has been deprecated. If you are still receiving this message with the latest TUFLOW release, please contact support@tuflow.com.
The Control Number Factor must be in the range 0.001 - 1.2.

Suggestions
Ensure the 'Control Number Factor' TCF command is within the range 0.001 - 1.2. The default value is 1.0.

Whilst it is possible to increase the default HPC Courant, shallow wave celerity and diffusion control numbers (effectively overclocking the simulation), it is strongly recommended not to increase the Control Number Factor above the default of 1.0. A hard upper limit has been set to prevent an increase of more than 20% (i.e. Control Number Factor == 1.2). Increasing control numbers by more than this would be likely to lead to instability.
