But
===

Project matrices and/or vectors assembled on a modal basis or on a RITZ basis. The matrices and vectors projected results will be used by generalized component calculation algorithms (DYNA_TRAN_MODAL [:external:ref:`U4.53.21 <U4.53.21>`] for example).

This macro command replaces the following successive commands:


* NUME_DDL_GENE [:external:ref:`U4.65.03 <U4.65.03>`] which establishes the numbering of the generalized degrees of freedom,


* one or more occurrences of PROJ_MATR_BASE [:external:ref:`U4.63.12 <U4.63.12>`] to project one or more assembled matrices,


* one or more occurrences of PROJ_VECT_BASE [:external:ref:`U4.63.13 <U4.63.13>`] to project one or more assembled vectors.
