from documentation [1]: "An engine maintaining constant stresses or
constant strain rates on some boundaries of a parallepipedic packing. ...".
So according to the documentations it is not designed for cylinders.

you can have a look at [2], it is a script for compression with lateral
confining stress modeled by loaded facets. After some modifications
(introducing the same concept also for axial direction) it may be what you
want

It depends on the definition of cyclic loading (axial compression?), but
basicly it should not be a big problem..

cheers
