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
controls
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.
cham_no
calculated will contain:
·
the 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
INFORMATION
INFORMATION = impr
Parameter of impression:
1
: (defect) not of impression,
2
: impression of
cham_no_ *
result.
4 Examples
An example of using sequence of controls
CALC_CHAR_CINE
is given in
documentation of the control
AFFE_CHAR_CINE
[U4.44.03].
