Prerequisites

• OpenFOAM (recommended: v5.x or compatible)
• CFDEMproject
• C++ compiler (GCC recommended)
• Linux environment

Build Instructions

1. Clone this repository and the CFDEMproject sources.
2. Set up OpenFOAM and CFDEMproject environment variables.
3. Navigate to the solver directory:

   cd cfdemSolverIB_VOF
   wmake

4. The executable will be created in your user application directory.

Running Simulations

1. Prepare your case directory with mesh, initial fields, and configuration files.
2. Running the solver:

   cfdemSolverIB_VOF

3. Post-process results using OpenFOAM utilities or ParaView.
