**r7.10.03** Post-processing of tree line calculations: Campbell diagram
==================================================================================

**Summary**:

This document presents the CALC_MODE_ROTATION and IMPR_DIAG_CAMPBELL commands for monitoring the modes of rotating machines according to the speed of rotation as well as the zones of instability of these modes. First, we recall the definition of this tool, then we detail its organization chart. Finally, the main steps of the corresponding algorithm as designed and implemented in*Code_Aster* are presented.
