Operator CALC_CHAR_CINE

1 Goal

To calculate the field with the nodes corresponding to the degrees of freedom imposed by AFFE_CHAR_CINE.

This field with the nodes thus calculated will have to be used at the time of the resolution of the linear system with
operators RESO_LDLT [U4.51.02] or RESO_GRAD [U4.51.04].

This operator is useful only for calculations “step by step” where one solves the linear systems by
commands RESO_LDLT or RESO_GRAD.

Product a structure of data of the cham_no. type.

3 Operands

3.1 Operand
NUME_DDL

NUME_DDL = naked

Name of classification associated with the matrix which will be used for the resolution.

3.2 Operand
CHAR_CINE

CHAR_CINE = l_chci

List names of the loads kinematics to be evaluated.

The calculated cham_no will contain:

·
value 0 on the degrees of freedom which are not imposed,
·
the specified value by the loads kinematics on the degrees of freedom which are
imposed.

Caution:

If a degree of freedom is imposed several times (if it appears in several loads
kinematics of the list l_chci), the specified value on this degree of freedom will be the sum of
specified values, which is undoubtedly not what the user wishes!
This dangerous behavior is unfortunately supplied with no alarm.

If the kinematic load is of function type, the specified value in a degree of freedom is
that obtained by evaluation of the function to the co-ordinates of the node carrying the degree of freedom
and at the moment T [§3.3].

3.3 Operand
INST


INST = T

Moment being used to evaluate possible functions of time [§3.2].

3.4 Operand
INFO


INFO = impr

Parameter of impression:

1: (defect) not of impression,

2: impression of the cham_no_ * result.

4 Examples

An example of sequence of commands using CALC_CHAR_CINE is given in
documentation of command AFFE_CHAR_CINE [U4.44.03].
