Abstract: 

A NUMBER OF MOTION STRATEGIES TO HANDLE FLUID FLOW INVOLVING MOVING BODIES HAVE BEEN APPEARED OVER THE LAST TWO DECADES. THEY ARE FREQUENTLY USED IN MARINE APPLICATIONS TOGETHER WITH FINITE VOLUME DISCRETIZATION AS IN THE CASE OF AUTHORS UNDER DEVELOPMENT SOFTWARE. AN APPROPRIATE CHOICE AMONG SUCH STRATEGIES STRONGLY HELPS TO CATCH DESIRED CODE CAPABLE OF MEETING ALL REQUIREMENTS WHILE KEEPING THE COMPUTATIONAL EFFORT AT AN ACCEPTABLE LEVEL.
IN THIS PAPER, SUCH STRATEGIES ARE BRIEFLY DISCUSSED IN SIX CATEGORIES AND ASSESSED BASED ON COMMON NECESSITIES IN THE AREA OF MARINE STRUCTURE HYDRODYNAMIC PROBLEMS. FINALLY, SOME RESULTS ARE PRESENTED USING TWO DIFFERENT MOTION STRATEGIES IN THE UNDER DEVELOPMENT SOFTWARE. BODY-ATTACHED MESH IS IMPLEMENTED TO CALCULATE A THREE DIMENSIONAL (3D) BARGE RESISTANCE IN A TWO DEGREE OF FREEDOM (2-DOF) STEADY FORWARD MOTION AND ALSO OVERLAPPING MESH TO INVESTIGATE A 2D CYLINDER SLAMMING IN A 1-DOF FREE FALLING.
