# Natural Frequency Response

Create a Design Response that measures the smallest natural frequency of the FE model for a set of boundary conditions. The response is computed by f = min\_{i=1..N}(|f\_i - f\_0|), where f\_i represents the N smallest natural frequencies obtained by solving a linear modal finite element analysis, and f\_0 is an offset value.

### Inputs

| Number of modes | [Integer](../../../../block-documentation/types/integer) | Number of modes that will be searched for and included in the response computation. |
| Frequency offset | [Scalar](../../../../block-documentation/types/scalar) | Frequency offset used in the design response computation. |
