# Global quantities available for postprocessing

## Introduction

The global quantities available in Steady state AC are listed in the following blocks.

The global quantities are stored by category in function to the computation:

- Region: for a computation on spatial support (region, volume, face…)
- Component: for a computation on an electrical component
- Mechanical set: for a computation on a mechanical set

This part concerns only the quantities computed on « Region »

## Usual global quantities (Region)

The usual global quantities available for a computation on a spatial support are presented in the table below.

- 2D plane:
- the modulus of the vector
- the orientation of the vector
- the both components on X and on Y of the vector

- 2D axi :
- axial component: axial vector modulus
- radial component: angular density of the vector
