HELIUS_MICROMECHANICS_HEXPACK
HELIUS_MICROMECHANICS_HEXPACK can be called to run the hex-pack micromechanics FEA routine.
This can be useful for determining the composite elastic constants from a set of constituent level data.

- FVF_FEA
The fiber volume fraction used in the micromechanics subroutine. The fiber volume fraction used during the analysis may be slightly different than the fiber volume fraction specified in the
Composite Material Manager interface. Due to the nature of finite elements and the micromechanics model, the round edges of the fibers are modeled by elements with straight edges. Therefore, the actual fiber volume fraction used during the analysis may vary by a small margin.
