Introduction
The LMGC90 post-processing relies on a list of commands in the same way that the list of CHICcommands used in the file COMMAND.DAT. The post-processing command are located in thePOSTPRO.DAT file in the DATBOX directory.
The post-processing action are decomposed in three phases:
Before computation phase used to analyse the initial data of a simulation.
During computation phase used to recup and store informations during the simulationprocess.
After computation phase used to analyse the final state of a simulation.
This natural decomposition is reproduced using CHIC command related to post-processing.
The post-processing could be performed during the simulation or using the Vloc Rloc.OUT andDOF.OUT output files.

Introduction
If the post-processing will be performed during the simulation, the user needs to add some extracommands in the file COMMAND.DAT:
START POSTPRO to store all commands which must be used and initialize thepost-processing structure.
POSTPRO DURING COMPUTATION to scan commands which must be executed duringthe simulation process.
POSTPRO AFTER COMPUTATION to scan commands which must executed after thesimulation
If the post-processing will be performed using output files, the user does not need to launch againthe simulation. The command file must be changed a minima,using the previous command andthe following ones:
INIT POST DATA to init data and specify the first and last ID files to read (give on the linesafter the command).
UPDATE POST DATA to update the output file to read.
In both cases, the resulting files are written in the POSTPRO directory.
