Is it possible to homogenize aperiodic/partially periodic structures using 3D FEA?

    Dear sir, 
    apart from MSG? is there any alternate way to predict effective properties using 3D FEA  for aperiodic/ partially structures such as honeycomb core, circular fiber with circular matrix interphase (CCA model),   if so please me suggest me because I want to compare my MSG results with 3D FEA/some other approach

    The following paper can help you, at least for honeycomb core, but not for CCA. For CCA you can use analytical solutions found in textbooks. The ultimate validation will be direct numerical solutions. J. J. Espadas-Escalante, N. P. van Dijk, P.

    Dear sir thank for your kind reply, sir  i had tried honeycomb structures using PBC in Abaqus but it is not satisfying periodicity  is it  possible to apply periodic BCS  for honeycomb structures  if so  then suggest some paper using 3D FEA
