1. But

Project a matrix assembled on the basis of mechanical eigenmodes or on the basis of RITZ. The projected result matrix will be used by generalized component calculation algorithms (DYNA_TRAN_MODAL [U4.53.21] for example).

You can use PROJ_BASE [U4.63.11] to process multiple matrices simultaneously.

Produce a generalized matrix concept of type Matr_asse_Gene_R if the assembled matrix to be projected is of type Matr_asse_Depl_R or type Matr_asse_Gene_R.

Produce a generalized matrix concept of type Matr_asse_Gene_C if the assembled matrix to be projected is of type Matr_asse_Depl_C or type Matr_asse_Gene_C.
