Composite layups in fully coupled thermal-stress analysis

Hi!

I work with Abaqus v6.12 in the field of composite materials and I am trying to carry out a fully coupled thermal-stress analysis with using composite layups of 3D continuum elements and I get this error message: LAYERED MATERIAL PROPERTIES CAN NOT BE SPECIFIED FOR THIS ELEMENT TYPE. Is it not implemented in Abaqus the posibility to carry out a fully coupled thermal-stress analysis with using composite layups of 3D continuum elements?

I got problems carrying out a fully coupled thermal-stress analysis with using continuum SHELL elements too (Messages like: 400 elements having missing properties...).

I would really appreciate your help.

Thank you very much!
