# Update Optical Properties
After running a heat simulation, you can use the temperature data to update the material's optical properties. This is a convenient feature for coupling different solvers.
Only mediums including Optical Perturbation specifications will be updated.
# Use results from
Select the solver from which to take the results.
# Temperature monitor
Select the temperature monitor from which the optical properties will be updated.
# Interpolation method
interp_method: Interpolation method to obtain heat values that are not supplied at the grid coordinates.
Options:
- nearest
- linear
Default: nearest
# Auto update
Set it to True to automatically update the material's optical properties when new temperature results are available.
