"Extended" maps
=================

A CARTE is a field that is affected by cells or groups of cells. Data structure CARTE is "condensed": facing each other instantiated quantity, the list of cells affected by this quantity is stored. In CALCUL, the basic problem for using CARTES is the following: "how to find the instantiated quantity associated with the ima mesh in order to be able to copy it into the local field provided to the TE00IJ routines? "

This problem cannot be solved effectively with the CARTE structure (especially if you think that a mesh can be affected several times: "overload" principle), which is why at the beginning of CALCUL (routine DEBCAL), we "extend" the CARTES "IN" (routine ETENCA), we "extend" the "INS" (routine). This extension consists in creating for each CARTE, 2 additional temporary objects that allow you to do the association (mesh, size) once and for all.

These 2 objects correspond to the following SD CARTE_ETENDUE:


.. code-block:: text
 CARTE_ETENDUE (K19): := record
'$ VIDE ': CARTE
'. PTMA ': OJB S V I LONG = nb_ma
'. PTMS ': OJB S V I LONG = nb_ms

Object '. PTMA ':

let nb_ma be the number of meshes of the mesh associated with the map,

for ima=1, nb_ma:

. PTMA (ima): number of the size associated with the ima mesh

Object '. PTMS ':

let nb_ms be the number of additional Ligrel cells associated with the map,

for ims=1, nb_ms:

. PTMA (ims): number of the quantity associated with the additional mesh ims
