Moment Application to lumbar spine model
Hello,
i have a "little" problem regarding application of a torque. I have a model of the lumbar spine (L1-L5). I want to apply a torque on the first vertebra (L1). After the simulation finished (Solver: Radioss) and i look at the results, i can't detect any movement in the model (i have constrained L5 in all 6 DOF, but nothing else). Does anybody know what could be the solution to this problem? Thanks in advance!
I tried to attach the rad Files but they are too large. I have copied the (imo) relevant section below.
Cheers, T

Hi
The /CLOAD is using the grnod id 31.
Is this the Grnod you want to use? or is the Grnod id 9 as listed on your message?
