Out of Gerris and the scripts we get (not quite) dimensionless coefficients that can be used to compute forces and moments in a JSBSim hydrodynamics configuration. | Out of Gerris and the scripts we get (not quite) dimensionless coefficients that can be used to compute forces and moments in a JSBSim hydrodynamics configuration. | ||
As an example, take the buoyancy function for the left float on the MFI-9B aircraft, shown below. The coefficient table is indexed by the the position and orientation of the float relative to the surface of the water and encodes the shape and position of the float. It is redimensioned using the density of the fluid and the local gravitational acceleration, so it can e.g. be used in both fresh and sea water by adjusting the density property. | As an example, take the buoyancy function for the left float on the MFI-9B aircraft, shown below.
