Does anyone have any experience using the solidVelocity boundary condition? I've tried to test it out but I get floating point exception errors whenever I try and use it, and there are no examples in the tutorials that I could find. Thanks!

Explain your problem, there may be more appropriate boundary conditions that match your case.
BTW, I only found this:

Description
    Velocity boundary condition with boundary non-orthogonal correction for
    the solid solvers.

    Essentially time-varying fixedValue with non-orthogonal correction.

    Optional time-varying velocity specified via a velocitySeries.

Hi,

You can use solidVelocity for the displacement field (D) or displacement increment field (DD) as follows, for a velocity that is constant in time:

    yourPatchName
    {
        type            solidVelocity;
        velocity        uniform (1 2 3); // set velocity here
        value           uniform (0 0 0);
    }

or for time-varying as:

    yourPatchName
    {
        type            solidVelocity;
        velocitySeries
        {
            fileName    "$FOAM_CASE/constant/timeVsVelocity";
            outOfBounds clamp;
        }
        value           uniform (0 0 0);
    }

where timeVsVelocity gives the time vs velocity in the following form (time on left, velocity on right, actual velocity will be interpolated from this table):

(
    ( 0    ( 1 0 0 ) )
    ( 4    ( 1 0 0 ) )
    ( 6    ( -1 0 0 ) )
    ( 10   ( -1 0 0 ) )
)

I have attached an example plateHole case showing this usage.
