Yes. Go back to CAD and slice the body using two planes running through the center. Use Shared Topology to connect the four pieces. That means use the Share button on the Workbench tab in SpaceClaim or Form New Part in DesignModeler. Now you have a vertex at the center and a vertex on each edge. Apply a Displacement of X=0 and Y=0 at the center vertex, and a Displacement of Y=0 at the vertex on the left edge. That works in a 2D analysis. You need to do three points for a 3D analysisn
