Residual stress requires path-dependent nonlinear material properties (plasticity) and the elevated stress free temperature of the molten material.  The effect of molten material cooling is almost entirely tensile, so your result doesn't surprise me too much.  Are you plotting a signed quantity like SX or an unsigned quantity like SEQV?
