Which Δt is used in the dualsphysics simulation

As shown in the XML 4.0 Guide,

Where can I find this Δt value of the simulation?

Does it change or constant for a simulation?


  • As you can see in the formulation it changes at each step, so that it is variable.
    There is an option in DualSPHysics that allows you to save an output file with the used time steps (check the "help" of DualSPHysics, please). However to have a first idea you can just divide simulation time between total time steps.

  • May I know in which source code file has this Δt expressions.
