Modal analysis
**************

Perform a modal analysis of the system. It can help to check if all interfaces
and links are well defined. Uses overall mass and stiffness of a structure to 
find the various periods at which it will naturally resonate. It uses the mass
and stiffness matrices to find the modes of the machine. Physics type shows if it
is a mechanical or thermal analysis. 

--------------
Axis positions
--------------

Move the axis defined under kinematics to the desired position. (0,0,0) is 
the default position.
