There are two approaches to Moldflow Shrinkage/Warpage simulation. CRIMS and non-CRIMS. Either approach can be used for running Fill + Pack + Warp , a simulation that solves for filling, post-filling, shrinkage and warpage of the part. Additionally, with CRIMS data you can run the MF/Shrink (Fill+Pack+Shrink) simulation which determines a recommended shrinkage allowance that can be used to cut the mold. The simulation will provides an indication of whether critical tolerances can be met with this allowance and also a spatial representation of the validity of this allowance across the part.
