I am currently trying to model a coupled temperature-displacement analysis of a CFRP using Abaqus 6.14-3. As the mesh distortion is very high, I am using the CEL (Coupled Euler Lagrangian) analysis.
How have currently modeled the CFRP as a small rectangular part, and have partitioned it as 2 areas- one having an isotropic material, and the other an anisotropic material.I have used the Volume Fraction Tool to define the areas.
The Abaqus code for providing a material orientation directly, when having more than one material definition, has many bugs and hence does not allow the material orientation. Anyone has any experience with the same (providing an anisotropic and an isotropic material definition in a CEL analysis)?
Or is there any other way to better model a CFRP, and check do a coupled temperature-displacement analysis?
Any help would be appreciated.

I did the same thing using ANSYS, there is an option for setting the " element coordinate system". You may check if something equivalent is available in Abaqus.

Thanks Mr. Veerappan for the reply.
The option is available for Abaqus normal analysis. But the same is not available for CEL analysis, for more than one materials. One can only define the orientation of a single material inside an Eulerian domain, but not more than that.
I am trying to find ways to achieve the latter.
