B modeling: D_ PLAN
========================

D_ PLAN modeling. Static analysis with elastic behavior.




Optimization settings
-------------------------

     Parameter values are the same as for plane stress modeling except for the following value:


* Control of pseudo-random variables INIT_ALEA = 2




Basic structure built
----------------------------

Picture 3.2-1: Basic structure:D_ PLAN

The basic structure is thus built within the macro command CALC_BT based on the results of the 2D modeling and by considering the parameters previously.
