determining engineering constants using forcite in material studio

Hello everbody,

can anyone help me in finding the way to how to strain the unit cell (created using amorphous cell) with periodic boundary conditions only in one direction whether x,y or z, using forcite module, while we know that the strain tensor in forcite cotains all the diagonal terms as active ( hydrostatic strain field) when calculating the mechanical properties/engineering constants.

Secondly, I also want to know how to insert a nanotube in axial direction after creating a equilibrated and relaxed unit cell (amorphous cell) Epoxy resins.

I am very new to this simulation package and will highly appreciate any help.
