How to calculate the internal nodal forces with the displacement field

Hello everyone,

I would like to obtain the Internal Nodal Forces with a given field of displacement.
Is there a command that can do this?

I've seen the document of the command "CALCUL()", but I don't understand why I should offer DEPL, INCR_DEPL, SIGM and VARI at the same time, as presented in the syntexe.

In fact, I would like to calculate the elementry vector of this internal nodal forces, and I want to obtain the assembled vector by using the command ASSE_VECTEUR(). Any one knows if it is possible?


Thanks for your help.


Best regards,


Zhe

Hi.

I have the same problem. Did you figure out how to calculate internal forces?

Hi

you have to have a look on the documentation U2.04.06 : How to dig a tunnel and the test-case sslp105b.comm

You will find the methodology starting from line :

#    2EME PHASE BLOCAGE DU BORD DE LA GALERIE (OPTION DIDI)

up to the line

#        3EME PHASE = REINJECTION DE LA REACTION
