# fieldAtPoint (1d, 2d, 3d)¶

Record a field at a particular point in space

## Data¶

in (string vector, required)
Sampled Data
The first variable is the data we will be sampling
bin
The second variable is the bin used to determine what cell the point is located in.
out (string vector, required)
Output dynVector where the result of the operation is stored

## Parameters¶

point (vector float)
This is the point where the data will be computed
inpIndices (vector integer)
These are the indexes of the input array that will be stored in the output vector

## Example¶

<Updater computeValues>
kind = fieldAtPoint1d
onGrid = domain
point = [-0.25,0.0,0.0]

inpIndices = [0, 1, 2]
in = [em, cellBin]

out = [E]
