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! 📧 For queries or collaboration: [email protected]
