Adding fastener at the beggining of restart analysis?

[an318is]

Hi,

Does anyone know if it is possible to add a fastener at the start of a restart analysis. Im using the following code to try; however, I get a "system error code 5". Can someone tell me if it is possible, and i just have something going wrong, or no its not possible? I would have thought if it isnt possible it would say so, not give a system error.

*FASTENER PROPERTY, NAME=swproperty
5
*FASTENER, INTERACTION NAME = fast01, ELSET = spot_weld01, PROPERTY = swproperty
0, 1, 0
lower_part_surface, upper_part_surface

fast01 is a CONN3D2 element with a BEAM connector section assigned to it. Also, the connector element and section are defined in the original analysis, not sure if this may be contributing to the observed error. I tried having them in the restart file, but it told me they were not defined when i tried to access them in the fastener definition.

Thanks in advance
Adam
