3. Operands#

3.1. Operand MATR_ELEM#

♦ MATR_ELEM = honey,

Name of the matr_elem_* concept to be assembled.

3.2. Numbering and storage#

♦ NUME_DDL = naked,

Specify the numbering of the equations of the assembled system and the storage of the matrix.

3.3. Operand CHAR_CINE#

◊ CHAR_CINE = cha,

Name of the kinematic load to be taken into account in the assembled matrix for treatment by eliminating the imposed degrees of freedom (see command AFFE_CHAR_CINE [U4.44.03]).

3.4. Operand SYME#

to SYME = “OUI”

This argument can only take the value “OUI”. In this case, the symmetrization of the matrix is forced after assembly. Thus, if the matrix created by K assembly is non-symmetric, the keyword SYME = “OUI” makes it possible to symmetrize it and replace it with:

\(\mathrm{ma}=\frac{1}{2}(K+{K}^{T})\)

3.5. Operand INFO#

◊ INFO

Allows the printing of information on the assembled matrix

1:

no printing,

2:

impression of the number of terms stored and the conditioning coefficient of degrees of freedom of type “LAGR”,
