Restrictions :
The selected groups of elements must be previously defined.
Note
The results about the required groups are stored in the file Analysis_Name_TYP_ICH1_ICH2_ENV_from_DEBs_to_FINs_Group_Name.txt
TYP may be TEFF, DISP, CURV, ANG or BANG
Envelop outputs are not available for TYP = SWELL (ICURVTOT = 6)
Example :
*POSTENV
2 1 1 0 0
0 500 1 0
1
The resulting file is a csv format file named:
Analysis_Name _TEFF_1_1_ENV_from_0s_to_500s_Group_Name.txt
It contains the dynamic envelop of effective tension along the selected group between t=0s and t=500s.
