CALCULATION OF INERTIAL CHARACTERISTICS
=======================================
.. _CALCULATION_OF_INERTIAL_CHARACTERISTICS_:


C3D geometric kernel calculates the modeled object surface area, volume, center of gravity, and moments of inertia. In the general case, numerical integration is used. Volume integration is reduced to modeled object surface integration using the Gauss–Ostrogradsky theorem. Surface integration uses triangulation of a two-dimensional domain of definition of surface parameters. When the above characteristics of the model are calculated, it is possible to include ready-to-use data for particular model elements.
