      To change the Time Step Size using the TUI command (for example, to 1[s]), enter the following: /solve/set/time-step 1.0 When you use the following journal file, the Time Step Size is 0.2 [s] for 10 Time Steps then 0.5[s] for another 10 Time steps.
      /solve/set/transient-controls/time-step 0.2
      /solve/dual-time-iterate 10 30 /solve/set/transient-controls/time-step 0.5
      /solve/dual-time-iterate 10 30
