Volume 13 analyses the structural and functional properties of the internal quantities essential for describing vortex‑mechanical and rotational processes within the Monistic Continuum Model (MCM). The examined quantities are classified as primary or derived structural fields and are characterised with respect to their role within the internal architecture of the model. The volume describes the mechanisms through which these quantities are generated, organised, and embedded into internal relations. Spatial and temporal variations are formalised, structural consistency conditions are defined, and the implications for dynamical operators and equations are examined. Special attention is given to boundary cases such as vanishing, strongly pronounced, or direction‑dependent structural contributions. Volume 13 provides the foundation for the dynamical and process‑related development of the MCM in the higher volumes and ensures that vortex‑mechanical and rotational structures are consistently integrated into the internal model architecture. Note on Version 3.2 This edition contains no substantive or scientific changes compared to the original release. Version 3.2 adds only refined, model‑consistent graphical representations that enhance structural clarity and didactic transparency. The theoretical argumentation, terminology, and model architecture remain unchanged.
