Shell to Solid bonding Errors

We have a truss that we want to analyze just one joint so to save time we have most of it as shell elements and the joint in question as solid.  When we try to run the simulation we get an error stating that the contact between the solid and shell is no good.  Does anyone have a suggestion as to best way to connect these two?

Attached are some screen shots with the solids highlighted…
