.. _NeurEco PFS:

NeurEco Parametric Frequency Sweep
=====================================

NeurEco PFS (Parametric Frequency Sweep) template aims at predicting frequency responses of parameterized systems. 
It is your solution to perform optimal design of electromagnetic or mechanic structures.

NeurEco PFS takes as inputs real scalar parameters. The first one is dedicated to the frequency. 
The other ones can represent design parameters or material properties for example. 
Its targets are complex values representing the frequency response of a system (field, values of a scattering matrix, ...). 

To perform accurate predictions of the frequency response of a system, NeurEco PFS models the behaviors of the poles of the system with respect to the parameters in an implicit manner.

**NeurEco Dynamic** requires *neureco_pfs* license. 
This license gives access to all functionalities for **Parametric Frequency Sweep** except for the export of the model to the formats other than the native binary files.

An add-on license *neureco_embed_pfs* is a license specific for export to FMU format (see, for example, :std:ref:`Export NeurEco Parametric Frequency Sweep model with GUI`).
