[Solvd]How to inclde stress frm previous load case was created by Mihir
hey guys,
I am trying to implement a soil model, where my first stage is to determine the in-situ stress( the stress without any external loading, under the action of gravity). In the next stage, which is excavation, I need to include in my nodes the stress of the earlier case before doing the computation. How can I achieve this? [ Is it through crea_champ ?] Is there some tutorial that I could refer for this?
Thanking in advance,
d_riel

Hello d_riel,
that shouldn't be a problem. CREA_CHAMP is indeed the right solution.
Something like this should work:

Something like this should work:
RESU0 = (....initial calc with gravity
...INST_FIN=tFIN....);
SIGM0 = CREA_CHAMP(TYPE_CHAM='ELGA_SIEF_R',
OPERATION='EXTR',
RESULTAT=RESU0,
NOM_CHAM='SIEF_ELGA',
INST=tFIN);
RESU1 = STAT_NON_LINE(ETAT_INIT=_F(SIGM=SIGM0),
...);Best regards,

Hey Richard!
Thanks a lot, thats really helpful. Can you also tell me why we are using INST_FIN?

Hello d_riel,
its no neccessity to use INST_FIN, it was just to indicate a time step, because with CREA_CHAMP you can only extract one time step of a field.
