# Mesh: Tensor: CreationΒΆ

For tensor meshes, there are some functions that can come in handy. For example, creating mesh tensors can be a bit time consuming, these can be created speedily by just giving numbers and sizes of padding. See the example below, that follows this notation:

```
h1 = (
(cellSize, numPad, [, increaseFactor]),
(cellSize, numCore),
(cellSize, numPad, [, increaseFactor])
)
```

Note

You can center your mesh by passing a ‘C’ for the x0[i] position. A ‘N’ will make the entire mesh negative, and a ‘0’ (or a 0) will make the mesh start at zero.
