- | ===== 1. Description ===== | ||
- | |||
- | A center of gravity and mass extractor for interactions has been implemented in Metafor. | ||
- | |||
- | The synthax is the same as other extractors: | ||
- | |||
- | < | ||
- | |||
- | </ | ||
- | |||
- | Since the evolution of the density is not directly tracked in Metafor, in order to take into account the density variation for the computation of the center of gravity and for the mass, the mass matrix is directly employed. | ||
- | |||
- | <note important> | ||
- | To compute the center of gravity and the mass of an interaction a density different from zero is needed. Pay attention, when you define your material properties, to explicitly define a $MASS_DENSITY$ different from zero, otherwise a $FATAL_ERROR$ is raised. | ||
