♦/RESULTAT = resu, [evol_elas, evol_noli, evol_noli, mode_meca, evol_ther,

comb_fourier, mult_elas, fourier_elas, dyna_trans]

Name of the concept result of type evol containing the field to be post-processed

/CHAM_GD = field, [fiel_no_ DEPL_R, fiel_no_ TEMP_R, cham_no_ SIEF_R, cham_elno_ SIEF_R]

Name of the concept of the field to be post-processed. The optional keyword MODELE must be filled in as soon as CHAM_GD is present.

3.2. Operands NUME_ORDRE/NUME_MODE/LIST_ORDRE/INST//LIST_INST/PRECISION/CRITERE#

See documentation [U4.71.00]

3.3. Operand NOM_CHAM#

♦ NOM_CHAM =/'SIGM_NOEU', [DEFAUT so mechanical]

/”TEMP”, [DEFAUT if thermal] /field, [K16]

Name of the resu result field whose values you want to record on a cut line. If this keyword is not entered, the stress field at the nodes calculated from the movements is projected by default for a mechanical result and the temperature for a thermal result.

Note:

The macro command treats all types of fields: NOEUD, , ELEM, ELNO.

It is not recommended to use for the field type ELNO, * because the result of projecting the field ELNO * by * ** * is sometimes a bit confusing. PROJ_CHAMP For a node, on retrieved its value in one of the cells that contain this node. More details in Chapter*3.13* [u4.72.05].

3.4. Operand MODELE#

◊ MODELE = model, [model]

The name of the model associated with the evol_xxx result concept. The model is required when projecting the field by PROJ_CHAMP.

3.5. Operand UNITE_MAILLAGE#

◊ UNITE_MAILLAGE = 25, [DEFAUT]

Specify the logical unit number in which the line mesh for the cut line is created. This unit is by default 25; the user is offered the possibility of modifying it in case the unit 25 is already assigned to another use in his study.

3.6. Operands VIS_A_VIS#

◊ VIS_A_VIS = _F (

♦ GROUP_MA_1 = GMA, [l_K8]))

This keyword factor is used by the PROJ_CHAMP operator and allows, with its GROUP_MA_1de operand, to restrict the range of the field to be projected. The user is invited to consult the [U4.72.05] documentation for more information.

3.7. Keyword LIGN_COUPE#

♦ LIGN_COUPE = _F (

A repeatable keyword used to define one or more cut lines.

A cut line is composed of segments with 2 nodes that can describe:

be a straight line,
either an arc or a circle,
or any broken line.

In the first case, the cut line is composed of a straight segment, defined by its two ends and a number of regular intervals that intersect it.

In the second case, the cut line is composed of homogeneous straight segments, whose union forms an arc, or in particular a circle.

In the third case, the cut line is defined on the basis of groups of nodes or groups of meshes of the mesh: the cut line is then the path defined by the succession of the nodes in the group.

3.7.1. Operand INTITULE#

♦ INTITULE = txt, [Kn]

Title label in the table to distinguish the different cut lines. If this keyword is not entered, the title label is equal to “l.cut (n) “where (n) is the occurrence number of the cut line.

3.7.2. Operand TYPE#

This keyword allows you to define the type of cut line you want to create. It can be identified as SEGMENT, GROUP_NO, GROUP_MAou ARC.

3.7.2.1. TYPE =” SEGMENT “#

The cut line is identified with a straight segment, defined by its two ends and by a number of regular intervals that intersect it.

3.7.2.2. TYPE =” GROUP_NO “#

The cut line is defined by the data of groups of nodes in the mesh supporting the fields: the cut line is then the path defined by the succession of nodes in these groups.

3.7.2.3. TYPE =” GROUP_MA “#

The cut line is constructed from the nodes of a group of elements made up of SEG meshes. The cut line is then the path defined by the succession of the reordered nodes in this group. If the line is closed, it must be specified by designating the origin and end nodes (for example with the keywords GROUP_NO_ORIG and GROUP_NO_EXTR). These 2 knots must be the same. To impose the orientation of the line, you can use the keyword VECT_ORIE.

For more details about these keywords, see the documentation for the NOEUD_ORDO keyword for the DEFI_GROUP command.

3.7.2.4. TYPE =” ARC “#

The cut line is similar to an arc or a full circle. It is defined by the following data:

a first point corresponding to the origin of the circular cut line,
a second point corresponding to the center of the circle,
an angle (expressed in degrees) to determine the end of the cut line,
the number of points making up the cut line,
a vector normal to the plane containing the cut line in 3D only.

3.7.3. Operand NB_POINTS#

♦ NB_POINTS = nb, [I]

Number of points on the cut line.

3.7.4. Operand COOR_ORIG#

♦ COOR_ORIG = (x1, y1, [z1]), [l_R]

Coordinates of the first point of the cut line: 2 real numbers in the plane, 3 in space. This keyword is used for TYPE =” SEGMENT “or TYPE =” ARC”.

3.7.5. Operand GROUP_NO_ORIG#

♦ GROUP_NO_ORIG = GnoA, [group_no]

Name of the node group that defines the first point on the cut line. This group should only contain one node. This keyword is used for TYPE =” SEGMENT “.

3.7.6. Operand COOR_EXTR#

♦ COOR_EXTR = (x2, y2, [z2]), [l_R]

Coordinates of the last point of the cut line: 2 real numbers in the plane, 3 in space. This keyword is used for TYPE =” SEGMENT “.

3.7.7. Operand GROUP_NO_EXTR#

♦ GROUP_NO_EXTR = GnoB, [group_no]

Name of the node group that defines the last point on the cut line. This group should only contain one node. This keyword is used for TYPE =' SEGMENT '.

3.7.8. Operand GROUP_NO#

♦ GROUP_NO = no, [grno]

This keyword makes it possible to extract values on a given group of nodes. In the case of processing fields at nodes, this is perfectly analogous to POST_RELEVE_T. This keyword is only used for TYPE =” GROUP_NO “.

3.7.9. Operands GROUP_MA and MAILLAGE#

♦ GROUP_MA = grma, [l_grma]

This keyword makes it possible to pass the group of elements of type SEG used to extract the nodes in order to reorder them before post-processing.

♦ MAILLAGE = email, [mesh]

Mail is the mesh concept containing the GRMA group of elements.

These keywords are used for the TYPE =” GROUP_MA “.

3.7.10. Operand DNOR#

◊ DNOR = (xa, ya, [za]), [l_R]

The vector to be passed to this keyword must be normal to the plane containing the circular cut line.

In 2D: it is useless (DNOR = vector \(Z\) of the global coordinate system)

In 3D: it allows you to define the direction of travel of the cut line (anticlockwise direction).

This keyword is used for the TYPE =” ARC “.

3.7.11. Operand CENTRE#

♦ CENTRE = (x0, y0, [z0]), [l_R]

Coordinates of the point corresponding to the center of the circle supporting the circular cut line. This keyword is used for the TYPE =” ARC “.

3.7.12. Operand ANGLE#

♦ ANGLE = theta, [R]

It corresponds to the angle of the circle supporting the circular cut line (expressed in degrees) which, based on its center, the origin point and the plane containing the cut line, determines the end of the cut line. This keyword is used for the TYPE =” ARC “.

3.7.13. Operands DISTANCE_MAX and DISTANCE_ALARME#

◊ DISTANCE_MAX = distmax, [R]

◊ DISTANCE_ALARME = distal, [R]

These keywords are useful for the PROJ_CHAMP operator.

If the distance between a node on the cut line and the cut mesh is greater than distmax, then this node will be ignored (no value reading on this node).

If the distance between a cut line node and the cut mesh is greater than distala, an alarm will be issued.

The user is invited to consult the [U4.72.05] documentation for more information.
