# Timestep bigger than simulation interval¶

Error

**Timestep bigger than the given simulation interval. Please adapt your simulation control settings.**

## 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**.
