What you'll learn
Identify and fix bad mesh cells that cause instability, poor convergence, and failed OpenFOAM simulations.
Apply rotating wall boundary conditions correctly and know when rotating walls are the right modeling choice.
Build efficient Multiple Reference Frame (MRF) simulations for steady-state rotating machinery problems.
Set up time-accurate sliding mesh simulations to capture true transient rotating interface effects.
Prescribe complex motion using dynamic meshes, including translation, rotation, and oscillation.
Simulate large relative motion and multiple moving bodies using robust overset mesh techniques.
Choose the correct motion modeling approach for any OpenFOAM simulation scenario.
Optimize advanced OpenFOAM simulations to reduce runtime without sacrificing solution accuracy.
Debug motion-related errors and stabilize simulations involving moving and deforming meshes.
Reuse provided master files to quickly set up new motion simulations with confidence.
Requirements
Basic understanding of how to run an OpenFOAM simulation - those who have taken my OpenFOAM course, The Ultimate Simple Beginner OpenFOAM CFD Course, will be completely ready for this course too.
Computer with OpenFOAM on it.
Description
This is an advanced, hands-on OpenFOAM course focused on real motion simulations — not CFD theory.Advanced OpenFOAM CFD: Dynamic Meshes And Motion is a practical, hands-on course designed for OpenFOAM users who want to simulate real-world motion accurately, efficiently, and with confidence.Motion simulations are where many OpenFOAM cases fail — not because the solver is wrong, but because the mesh, motion setup, or modeling choice is incorrect. This course teaches you how to avoid those mistakes and confidently model motion found in rotating machinery, vehicles, aerospace systems, and moving mechanisms.Rather than focusing on theory, this course shows you exactly how to set up, run, debug, and optimize advanced motion simulations in OpenFOAM.You will learn how to simulate motion using the most important advanced OpenFOAM techniques, including:Finding and fixing bad mesh cells that cause instability and divergenceApplying rotating wall boundary conditions correctlyBuilding efficient Multiple Reference Frame (MRF) simulationsRunning time-accurate sliding mesh simulationsPrescribing motion with dynamic meshesHandling complex relative motion using overset meshesChoosing the right motion approach for each problemReducing computational time and making simulations run fasterEach concept is demonstrated through real CFD simulations, not toy examples.This course walks through 7 complete CFD simulations, showing how to prescribe:Linear motionRotational motionOscillatory motionYou also receive master OpenFOAM files that you can copy, modify, and reuse for your own projects — saving hours of setup and debugging time.This course is ideal for:OpenFOAM users who already know the basics and want to move into advanced motion simulationsCFD engineers working in automotive, aerospace, turbomachinery, or rotating machineryStudents and researchers who need reliable motion modeling for real projectsThis course is not for complete beginners with no OpenFOAM experience.By the End of This CourseYou will be able to:Confidently simulate rotating, moving, and deforming geometriesDebug and stabilize motion-related OpenFOAM casesChoose the most efficient modeling approach for any motion problemRun advanced simulations faster and more reliablyIf you already know how to run basic OpenFOAM cases and want to simulate real motion, this course will take you to the next level.
Who this course is for
OpenFOAM users who already understand the basics and want to simulate rotating and moving geometries.
CFD engineers and analysts working on turbomachinery, automotive, aerospace, or rotating machinery simulations.
Students and researchers who need to model advanced motion such as MRF, sliding meshes, dynamic meshes, or overset meshes.
Engineers who want practical, copy-paste-ready OpenFOAM setups instead of theoretical explanations.
OpenFOAM users struggling with convergence, mesh motion errors, or long runtimes in motion simulations.
Anyone who has completed a beginner OpenFOAM course and is ready for advanced, real-world simulations.
Not for: Complete beginners with no prior OpenFOAM or CFD experience
If you already know how to run basic OpenFOAM cases and want to simulate real motion, this course is for you.
