## About this Block

**What it does:** Creates a field interpolated from Point Map data. The block creates a Scalar Field from an imported Scalar Point Map, or a Vector Field from a Vector Point Map.

**Common uses:**

* Converting simulation results into a field (which enables you to edit your part with the simulation results).

**Tips:**

* View the field using the Field Viewer (f).
* If the point map is collinear or coplanar, the block will not interpolate a field, and only extrapolate. The interpolation and extrapolation methods are described below:

**Interpolation**

* Linear: Values in between points are linearly scaled from the values of the nearest points.

* Natural: Values in between points are scaled while considering the nearest points and points further out, to smoothen out the interpolation.

* Nearest: Values maintain the exact value of the nearest point.

* Barycentric: Values are interpolated linearly from the three closest points, which define a tetrahedral. This method is recommended for point maps extracted from tetrahedral mesh, like  **Von Mises Stress Point Map** or **Temperature Point Map**.

**Extrapolation**

* Nearest: Values match the values at the end of the extrapolation region and extend outward with that value.

* Linear: Values scale outward from the trend of values of the field as it reaches the extrapolation region.

* Exponential: Values scale outward while considering the trend of multiple points sampled inward into the interpolation region.

* None: Outside of the interpolation region, the values are set to zero.
