Hi, I'm trying to run a simulation of a 3x3x3 cube in a 100x100x20 environment using the framework of the floatingObject tutorial. I'm just unsure of what the 'innerDistance' and 'outerDistance' are. Here's my dynamicMeshDict file... thanks

centreOfMass (50 50 10);

// Cuboid dimensions
Lx 3.0;

// Density of the solid

// Cuboid mass
