TUFLOW Message 2120
ERROR 2120 - There is no global timestep or a specific timestep for 2D domain.
There is no global timestep or a specific timestep for 2D domain. The global timestep is specified by using Timestep == outside a Start 2D Domain command block. For each 2D domain, as defined in the .tcf with Start 2D Domain and End 2D Domain, a timestep is specfied with a Timestep == command. If no specific timestep is applied to a 2D domain, the global timestep is used.
Specify a timestep for each 2D domain in the model and/or use a global timestep.
