Zero reaction force

Zero reaction force

Zero reaction force

(OP)
Hi All

I am doing a buckling Riks analysis , and I am having problems with the history out put results , on any node I have displacement , but reaction forces RF1 and 2 and 3 are zero , actually RF2 and RF3 are non zero in CAE visualization ( from field output ) but zero in the plot . do you have any suggestions ? is something going wrong in my solution ?

RE: Zero reaction force

(OP)
Anyone has an Idea ? also I try the reaction force in the fixed nodes , by the way , the fixed nodes are tied to a RF point through Rigid body , and the BC is on that point , any thing wrong ?
