Extraction into a table of values from a result on cut lines defined by two points and an interval or groups of nodes.

The result can be mechanical (evol_elas, evol_noli, modes_meca, comb_fourier, mult_elas, fourier_elas, dyna_trans) or thermal (evol_ther).

Principle:

This macro command creates a linear, straight, and regular mesh of segments with two nodes.

This mesh can be:


* straight, defined by the data of its extremities and the number of intervals composing it;


* curve, defined by the data of the center and the angle of a circle, the first point of the cut line, the number of desired points, and possibly a vector normal to the plane containing the cut line (in 3D only);


* any, when the cut line is a path connecting the nodes of a group of nodes.

The fields of the provided result (by default displacement or temperature) are projected onto this mesh using the PROJ_CHAMP command. Then the nodal values on the cut line of the field to be post-processed are retrieved from a table by POST_RELEVE_T. It is this table that is produced by the macro command.
