The model consists of a contained made of rigid 3D elements, a piston made of rigid shell elements, and water modelled with SPH particles. The issue I am having is when I apply gravity to the model using LOAD_BODY_Z and a load curve of 9.81 m\/s^2, the particles collapse to the ground. This is illustraded in the attached screen shots. Note that there is no leakage from the container, the particles simply fall straight down. Any help on this issue would be greatly appreciated.
