No Timestep 0 when running transient simulation after steady state simulation

      Dear all,


       


      I am simulating a reaction in a pipe.


      At first I run a steady-state simulation without the reaction so the flow and the temperature is already set.


      After the steady-state simulation I switch to transient mode and run the simulation with the reaction.


      I save the data after every timestep, but the timestep 0 ist not saved in the transient simulation.


      The first saved timestep is 1 when I look at the .dat files.


      I can export the solution after the steady state, but I need to create an animation.


      For that purpose I need to have the timestep 0 in the same data row as the other timesteps.


      Is there any possibility to get the timestep 0 when there is a transient simulation after a steady-state simulation?


      Kind regards
      Christopher

      You could save manually immediately after switching to transient.
