How to model hybrid composite in ABAQUS?

Hello everyone,

Good day! I am trying to model a hybrid composite in abaqus. But I am not being able to run it. So what I am trying to do is, I am using two types of fibers with two different diameters and materials in the matrix. As it is a test run, I am using steel as the matrix material, graphite as the larger diameter fiber and glass as the smaller diameter fiber. Again as a test run, I am applying fixed boundary condition at the left edge of the RVE and distributed normal stress at the right edge of the RVE. After meshing the RVE, I am trying to run it. But the simulation is being aborted again and again. The error message is like following-

"Anisotropic material properties without a local orientation system have been defined for 100 elements. Anisotropic material properties must be defined in a local orientation system. The elements are identified in element set ErrElemAnisotropicMaterial."

Could any of you please help me to fix this problem? Has any of you solved such kind of a problem before? It would be much easier for me if you could kindly share the steps you followed with me.

Thanks!
