This Python script (Random_Disc_RVE) is a simplified version of the EngSoft_RandRec_V1 Abaqus plug-in for generating random short fiber composite RVE in Abaqus.
It is ideal for mesoscale modeling of short fiber reinforced composites, including polymers and concrete-based materials.

🔹 Random Fiber Placement
The script places fibers randomly within the RVE using precise intersection checks, preventing overlaps and allowing reasonable volume fractions.

🔹 Variable Lengths and Orientations
You can define different fiber lengths and orientations for flexible microstructure modeling.

🔹 Material Assignment
Each fiber can be assigned individual material properties and orientation angles for accurate representation of the composite microstructure.

🔹 Boundary Handling & PBC
Fibers intersecting the RVE boundary can be recreated on the opposite side.
Boundaries are meshed for PBC-ready application using MPC constraints in Abaqus.

🔹Educational Version Limitations
This file is designed for academic and training purposes:

• Intersection checking is simplified, which may limit maximum volume fraction.
• Fiber-boundary intersection is partially implemented.
• Intended for learning and prototyping rather than high-volume industrial RVE generation.

🔹 Simplified Version Notice
This Python script provides a basic version of RVE generation.
For full features, including high-volume fraction generation and advanced fiber arrangements, please use the full EngSoft_RandRec_V1 Abaqus Plug-in.
