HRS Computing[1] is an open-source scientific software which simulates the hyper Rayleigh scattering (HRS) in nonlinear optics.

The software is designed for researchers, and it is used to verify the agreement between theoretical models and experimental data.

From the physics point of view the software provides coefficients that are useful for the determination of the microscopic structure of composites, molecules, etc.

Using these coefficients, the software also provides:
