Hi there,
I am analysing an assembly with countersunk screws. The normalbolts in the assembly have nice planar surfaces to apply the loadto etc However there are several countersunk bolts that have aconical seal obviously, but the cosmos does not like that when yousolve the analysis and keeps coming up with errors. I have beenselecting the outer edge of the countersunk hole and defining abolt head diameter.

If I cheated and filled in the countersinks the material would bethicker and give false results.

Any ideas on how to make it solve a countersunk bolt connector.

Many thanks
