[SOLVED] Resultant of FORC_NODA nodal foces on a (intenal) Group

Hi ,
i'm trying to get the resultant on group 'BASE2' , but it give me null result , on other groups 'BASE3' and 'BASE1' results are corrects.
Why this ?

Hello,
glad to hear that the resultant forces on free nodes equal zero otherwise the system would not be at equilibrium.

Yes,it is.
A way to obtain internal nodal forces like POUTRE in COQUES (Not linerar forces NXX,NXY...) ? The ideas is to subdivide structure in two part and obtain the reciprocals resultant internal forces that the tow parts exhanges beetwenn each others.

Simply when i extracted FORC_NODA whit CALC_CHAMP , instead of considering all structure , i have considered the "left" GROUP_MA (SEZ1) containng BASE2 , and the internal forces become external.
