4. Operands#

4.1. Operand MODELE/CHARGE#

♦/MODELE = mo, CHARGE = lchar

The code will number the degrees of freedom of the elements of the mo model as well as the degrees of freedom of dualization of the dualized kinematic conditions that may be present in the loads in the lchar list.

4.2. Operand MATR_RIGI#

♦/MATR_RIGI = lmel

List of matr_elem_* to establish the numbering of the unknowns of the problem.

The purpose of this operator is to number all the degrees of freedom in the problem. These degrees of freedom are those carried by the elementary matrices calculated by the operator CALC_MATR_ELEM (lmel).

Because of the dualization of the « kinematic » conditions, the Lagrange degrees of freedom are carried by the matr_elem calculated by the option “RIGI_MECA” (or “RIGI_THER”,…) on the loads where the kinematic conditions are defined.

It is therefore important to list all the « stiffness » matr_elems in lmel and not to forget the loads in the operator CALC_MATR_ELEM [U4.61.01].

4.3. Operand INFO#
