# inparam.nr.yaml

This file is only really relevant for when you start including 3D
models. 


For more details, see the section [Nr Field](../nr_field/index.md).

**type**
```
type_Nr: CONSTANT
bound_Nr_by_inplane: true
```

**constant**
```
constant: 5
```

In 1D, in a limited set of cases, and if you are really pushed
for computational resources, you can make a tiny saving by setting
`type_Nr` as `CONSTANT` and equal to `3` (if you’re only using a point
force/dipole source) or `1` if you’re using a monopolar (isotropic
pressure) source instead of the standard `5`.
