Hi, to change the actual displacement, you can change the draft of your structure in the SpaceClaim/DesignModeler by moving the whole structure up or down along the Global z-axis. However, this may change the position of the buoyance centre. To change the equivalent displacement, you can adjust the point mass mass value. You can also choose "Program Control" for point mass, which allows the program defines the point mass mass value based on the actual displacement.
