Hi @naveen_kumar and thanks for reaching out to us!

The first option would be to define your load with a time-dependancy (for instance 5000\*t) and let the **simulation interval** be 5 seconds and the **initial time step length** 0.5 seconds if you like. But please be aware that the simulation time is something like a “ **pseudo-time** ” to show you what would happen to the component if we would move it slowly (“quasi static”). If you want a “ **real** ” time-dependancy a dynamic simulation might be the best for you.

Another great post by my colleague @ahmedhussain18 that might help you: **[Table Upload CSV - Time Definition](https://www.simscale.com/forum/t/defining-variable-constraint-or-load/22617)**.

All the best!
