I’m using Python to operate the Abaqus GUI and create an RVE with PBCs. There is no interphase or interface material because the material is an Ox-Ox CMC. I’ll have to delete some of the elements to indicate porosity.
Is there anyone who has done something similar before?

If your problem is geometrically and you want to know how to use python to model this composite, I suggest referring to the links below. You can learn a lot about python. You won’t regret it.

Python scripting in ABAQUS Part1

Python scripting in ABAQUS Part 2

Just remember, you must know the relations needed for the modeling.

If your problem is to define material properties, I recommend using UMAT and VUMAT subroutine. You can refer to this link:

UMAT Subroutine (VUMAT Subroutine) introduction

Again, you need to know the equation of the composite material properties.

Best wishes.
