Develop the IC engine model (surface mesh)with the CAD software e.g. CATIA

Export the model to the grid generatorsoftware STAR-CD

Develop and generate the preferred meshfor moving mesh simulation

Identify and develop the sequence events according tothe crank angle and strokes occured in the IC engine

model to perform the moving mesh simulation

Write the macro programming language (scripts) insideSTAR-CD based on the events declaration done.

Write and execute the grid activation command to move outthe vertices position consistent with the events declaration

Examine, check and verify the developed movingmesh by accomplishing the mesh preview run
