Mass Properties Analysis Execution


The Mass Properties analysis follows the component priority rules and will compute the masses and inertias from individual bodies into the total. Components may have volume density, surface density (mass/area), or a combination. However, as of version 3.31.1, interior thin surface densities are ignored by the analysis, regardless of priority. For example, a tank of priority 1 with both surface and volume densities modeled entirely within a fuselage of priority 0 will only contribute its volume density to the mass while the surface density is ignored. To get around this limitation, a step-by-step approach is recommended in which different priority levels are analyzed separately and accounted for.
