# Timestep bigger than simulation interval¶

Error

## What happened?¶

The simulation stopped due to time step length larger than total simulation interval.

## What could be the possible reason?¶

This error occurred because the Time step length or Initial time step length value is more than the Simulation interval value under the Simulation Control. For example, if Simulation interval is set to the value of 1 and Time step length or Initial time step length to the value of 2, than this means that although the total simulation interval is 1, still the first time step of the simulation will be 2 which exceeds the total simulation interval and therefore simulation stops.

## What can I do now?¶

Give smaller value to the Time step length or Initial time step length compared to the Simulation interval. For example, if Simulation interval is set to 1, than give the value of 0.1 or 0.25 to the Time step length or Initial time step length.
