I am following a course and have done everything I can to make sure I've followed every detail thus far -- but my hull seems to not respond to the RBD bullet solver collision properly. I've tried the hull that came with the course and also made my own hull ( which is my eventual goal) . Would someone be so kind as to have a look at my scene file and see what is wrong with the geo of my hull? It must be something in how I modelled the hull. I followed the rules of watertightness but I just don't know why particles penetrate the hull... It has a thickness but maybe not enough? I appreciate any guidance you may have. Thanks in advance.

Your Static Object node needs more configuration. The easiest way to fix it is to throw away all the collision nodes inside FLIP_Sim_Main and move the Display flag of Pre_Boat_sim to the null OUT_Boat. Move up to /obj level, turn on the Display flag for Prep_Boat_Sim. On the Collisions tool shelf, pick the Deforming Object button and choose Prep_Boat_Sim for the target. Read the instructions at the bottom of the 3D viewport. Remember to press ENTER with your mouse over the 3D viewport to establish a collision setup that will work with FLIP.

Thank you very very much -- I am going to try this now. Cheers

Sorry to bother you again -- do I also get rid of the collision nodes in "BOAT_Sim" Network? I did what you instructed above but the hull falls straight through the sim....
