We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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