ICFD Simulation in LS-DYNA | Boundary Conditions Setup & Post-Processing Tutorial

In this video, we dive into ICFD (Incompressible Computational Fluid Dynamics) simulation in LS-DYNA, focusing on how to apply boundary conditions and perform post-processing for accurate engineering results.

You will learn:
✅ How to set up inlet & outlet boundaries (pressure, velocity)
✅ When to use no-slip and free-slip wall conditions
✅ How to define fluid–structure interaction (FSI) boundaries
✅ Tips to avoid common setup errors in ICFD
✅ Post-processing techniques to visualize pressure, velocity, and streamlines in LS-PrePost

Whether you are working on aerodynamics, hydrodynamics, or thermal fluid simulations, this tutorial will help you confidently set up boundary conditions and extract meaningful results.

📂 Covered Topics:

BOUNDARY_PRESCRIBED_PRES (Inlet pressure)

BOUNDARY_PRESCRIBED_VEL (Outlet velocity)

BOUNDARY_NOSLIP (Realistic viscous walls)

BOUNDARY_FREESLIP (Frictionless walls)

BOUNDARY_FSI (Fluid–structure coupling)

Contour plots, vector fields, and animation exports in LS-PrePost

💡 Pro Tip: Accurate boundary condition setup is the foundation of reliable CFD results — spend extra time here before running the solver!
