# Mode Solver
Mode solver tasks allow you to build and run mode analysis simulations to obtain optical mode quantities of interest, for instance, field distributions, effective indices, and group indices.
To create a mode solver task, follow these steps:
- Go to the Folders (opens new window) section.
- Click
New Simulation. - Select a
Folderto store the newly created task. - Choose the
ModeSolverstudy type.
After creating a mode solver task, go through the following items to set up the simulation:
Then, run the simulation and click the Post-Run Result button to access the results.
