ABAQUS Restart analysis zero solution problem

ABAQUS Restart analysis zero solution problem

ABAQUS Restart analysis zero solution problem

(OP)
Dear members,

I am attempting to perform a restart nonlinear static Riks analasis of a hollow tubular member subject to global bending at the ends. The links below show both the main input file and the restart input file.

I am getting a zero solution whenever I try to run the restart file in the usual way, but for the life of me I cannot work out why. Any advice would be appreciated immensely.

The critical moment occurs at a load factor of approx 1.8. The mesh resolution is coarse in these files so that they run quickly. Symmetry BCs are exploited in the model.

Kind regards,
Adam
