Transient

Calculate how the model evolves over a time interval from its initial state.

Where to find it

System Solver workspace; Model Builder → System Solvers

How to use it

Set Start time, Stop time and Time step, choose the time solver, then run and inspect multiple saved times in Results. Choose Run System Solver, then select the completed solution under Results.

Settings and initial values

Setting	Initial value
Start time	`0[s]`
Stop time	`1[s]`
Time step	`0.01[s]`
Input events	`[]`
Maximum solution steps	`10000`
Solver	`BDF2`
Store fields	`All`
Update probes	`Off`
Output probes	`All probes`

Result

Successful runs provide solution data for plots, tables and evaluations in Results.

Troubleshooting

Reduce the time step to check temporal accuracy. An output interval is not by itself a guarantee that fast dynamics are resolved.
