Introduction
Ships moving through head sea waves predominantly encounter heave and pitch motions while the other four motions (roll, yaw, surge, sway) are negligible. In this tutorial a wigley hull heave and pitch motion is simulated in head sea waves

This tutorial demonstrates how to do the following

 Use VOF multiphase model of Fluent to solve open channel flow

 Use open channel wave boundary condition to generate shallow waves

 Use Numerical Beach option to suppress the numerical reflection near the outlet

 Use dynamic mesh six-dof feature to model motion of the hull

 Restrict 4 degree of motions out of 6 degree using User defined Function - UDF

 Post-process the resulting data
