I have already modeled RVE for single fiber lamina and determined its properties but wanna know how to model RVE for more than one fiber specifically in ANSYS APDL.
Usually one lamina contains MANY fibers. The purpose of micromechanics is to simplify the problem by assuming a microstructure such as square array or hexogonal array. You can add more fibers into your RVE the same way as you created one fiber RVE. You might also want to try SwiftComp, a general-purpose constitutive modeling code for composites which cna reproduce 3D RVE analysis using ABAQUS or ANSYS with a small fraction of its computing cost and you don't have to worry abut boundary conditions or loads. Even your RVE does not need to be straight.The code is freely launchable in the cloud at https://cdmhub.org/resources/scstandard. We also developed interface with ANSYS, the effective properties are just one click away.

Respected Sir, Sorry I cudnt make my ques clear to you... I have already modeled and analyzed RVE with fibers of single type, for example Graphite. Now I want to determine the properties of intraply lamina with fibers of both graphite and boron in epoxy matrix by modeling a single RVE incorporating both types of fibers. So that the overall elastic properties of the lamina can be determined. How to do that??
If you can model one fiber, you just add another fiber with different material properties. But if you use ANSYS, you need to make sure to add the right boundary conditions to get it right. I will recommend you to read my article on introduction to micromechanics at https://cdmhub.org/resources/1036 to get the basic premises of micromechanics.
