This command is used to merge a file with the input. The data in the included file can be transformed (optional). A point in the original configuration $\mathbf{x}$ will be moved to location $\mathbf{x}'$ according to:

$\mathbf{x}' = \mathbf{x_1} + \left[ \begin{array}{ccc} \bar{x}_x & \bar{y}_x & \bar{z}_x \\ \bar{x}_y & \bar{y}_y & \bar{z}_y \\ \bar{x}_z & \bar{y}_z & \bar{z}_z \end{array} \right] \cdot \left[ \begin{array}{ccc} sf_x & & \\ & sf_y & \\ & & sf_z \end{array} \right] \left( \mathbf{x} - \mathbf{x_0} \right)$

where:

$\displaystyle{ \bar{\mathbf{z}} = \left\{ \begin{array}{lll} \bar{\mathbf{x}} \times \bar{\mathbf{y}} & : & \mathrm{mirror} = 0 \\ \bar{\mathbf{y}} \times \bar{\mathbf{x}} & : & \mathrm{mirror} = 1 \end{array} \right.}$

Note that the point $\mathbf{x}_0$ in the original configuration will be moved to $\mathbf{x}_1$. This is the base point for both scaling operations and rotations.

Mesh included twice, with and without offsets

As simple model where the same mesh file mesh.k is included twice, as is and with some offsets.
