♦ RESULTAT = resu
Name of a result concept of type result.
4.2. Selecting order numbers#
The use of the keywords TOUT_ORDRE, NUME_ORDRE, INST,… is described in the document [U4.71.00].
4.3. Selection of the elements concerned#
Thanks to the keywords TOUT =” OUI “, and GROUP_MA, the user can select the elements on which the calculations will take place.
Note: If the user selects elements that are not structural elements, they are ignored.
4.4. Keyword EXTR_COQUE#
This keyword is used to extract a field on a single sub-point for shell elements.
4.4.1. Operand NOM_CHAM#
The NOM_CHAM keyword is used to designate the fields to be extracted in the resu result.
The following are authorized:
SIGM_ELGA |
|
|
|
EPSI_ELGA |
|
|
|
SIEF_ELGA |
|
|
|
4.4.2. Operand NUME_COUCHE#
♦ NUME_COUCHE = Nucou, [I]
Number of the layer containing the subpoint to be extracted.
By convention, layer \(1\) is the bottom layer (in the normal sense) of shell elements.
4.4.3. Operand NIVE_COUCHE#
♦ NIVE_COUCHE =
For the nucou layer defined by NUME_COUCHE, allows you to specify the ordinate of the sub-point:
“INF” |
bottom layer order |
(inner skin), |
“SUP” |
upper layer order |
(outer skin), |
“MOY” |
Average layer order |
(middle sheet). |
4.5. Keyword EXTR_TUYAU#
This keyword is used to extract a field on a single sub-point for pipe items.
4.5.1. Operand NOM_CHAM#
The NOM_CHAM keyword is used to designate the fields to be extracted in the resu result.
Are allowed: (see 4.4.1)
4.5.2. Operand NUME_COUCHE#
♦ NUME_COUCHE = Nucou, [I]
Number of the layer containing the subpoint to be extracted.
By convention, layer \(1\) is the inner layer of an element TUYAU.
4.5.3. Operand NIVE_COUCHE#
♦ NIVE_COUCHE =
For the nucou layer defined by NUME_COUCHE, allows you to specify the ordinate of the sub-point:
“INF” |
bottom layer order |
(inner skin), |
“SUP” |
upper layer order |
(outer skin), |
“MOY” |
Average layer order |
(middle sheet). |
4.5.4. Operand ANGLE#
♦ ANGLE = delta, [I]
delta: angle in degrees (integer value), counted from the position of the generator of the pipe element.
Note: The sub-points of the pipes are spaced evenly in the thickness of the pipe as well as in azimuth. When the user indicates an angle that does not correspond geometrically with a sub-point (in azimuth), a linear interpolation is performed between the 2 sub-points that « border » the specified angle.
4.6. Keyword EXTR_PMF#
This keyword is used to extract a field on a single sub-point for multi-fiber beam elements.
4.6.1. Operand NOM_CHAM#
The NOM_CHAM keyword is used to designate the fields to be extracted in the resu result.
Are allowed: (see 4.4.1)
4.6.2. Operand NUME_FIBRE#
♦ NUME_FIBRE = nufib, [I]
Number of the fiber corresponding to the sub-point to be extracted.
4.7. Keyword MIN_MAX_SP#
This keyword is used to calculate the « maximum » (or minimum) value of a field component. The « max » being taken on all the sub-points.
If the input field is for example a ELGA constraint field on the subpoints of a multi-layer shell, the output field will be a ELGA field (without subpoints) containing for each Gauss point the « max » value of the constraint.
In addition to the « max » value, information is also extracted to locate the sub-point that has reached the « max ». In the end, on each « point », 6 components are calculated:
4.7.1. Operand NOM_CHAM#
The keyword NOM_CHAM allows you to designate the field to be extracted in the resu result.
Are allowed: (see 4.4.1)
4.7.2. Operands NOM_CMP/NOM_VARI#
◊ NOM_CMP = nocmp, [Kn]
Name of the component whose « max » we want to calculate.
◊ NOM_VARI = novari, [Kn]
For the fields of internal variables (VARI_ *), you can give the name of the internal variable whose « max » you want to calculate (see [U4.51.11] for the rules for naming internal variables).
4.7.3. Operand TYPE_MAXI#
This keyword is used to choose the « type » of maximum sought:
“MAXI” |
We extract the maximum value of the component taking into account its sign |
“MINI” |
We extract the minimum value of the component taking into account its sign |
“MAXI_ABS” |
We extract the maximum value from the absolute value of the component |
“MINI_ABS” |
We extract the minimum value from the absolute value of the component |
4.7.4. Operand NUME_CHAM_RESU#
♦ NUME_CHAM_RESU = nuch, [I]
The number nuch is used to name the product field.
For example, if NOM_CHAM = “SIEF_ELGA” and NUME_CHAM_RESU = 7, in the result data structure produced, the field will be accessible by NOM_CHAM = “UT07_ELGA”. This is the 7th field ELGA « UTilisateur » in the data structure.
Note: nuch is limited to 20.
4.8. Keyword COQU_EXCENT#
This keyword is used to modify the « plane » for calculating the generalized forces in eccentric plates.
The field found under the name NOM_CHAM in the input sd_result (resu) contains forces calculated in the mesh « plane ».
The eccentricity of the elements is taken into account to modify the calculation of the moments (they are calculated in the mean « plane » of the eccentric plate).
4.8.1. Operand NOM_CHAM#
The keyword NOM_CHAM allows you to designate the field to be extracted in the resu result.
The following are allowed: “EFGE_ELNO” and “EFGE_ELGA”.
4.8.2. Operand MODI_PLAN = “OUI”#
This keyword is used to confirm that we want to change the calculation « plane » for the forces in the eccentric plates.
