Hello all, I am attempting to use some RBE3 elements to apply loads and I am receiving this error: A fatal error has been detected during input processing: *** ERROR # 774 *** When a grid's component has no stiffness, then that component cannot be an independent d.o.f. in an RBE3. RBE3 id = 270584 grid id = 326669 weighted components = 123 max d.o.f with stiff = 1 Would greatly appreciate some advice regarding this. Thanks
I'm building RADIOSS model of a square plate under impulse loading to calculate the reaction force. The boundary condition is follows, -<A> full constraint on the 4 edges (RED in picture) and -<B> only translation in out-of- plane direction is constrained on some area of the plate(Blue in picture) In order to create this B.C.s, I used 2 RBODYs which share the same master node. The master node is fully constrained by SPC and output of REACX on that node is defined to output reaction force. Running RADIOSS returns ERROR 442, ** ERROR IN RIGID BODY DEFINITION DESCRIPTION : -- RIGID BODY ID : 47869 -- RIGID BODY TITLE : AT LEAST TWO RIGID BODIES USE THE SAME MASTER NODE ID=87278 I know switching either of RDOBYs to SPC will fix this problem but I can't get correct reaction force. Is there any way to go through this problem?
