3 possible shrinkage models usedBy default the most accurate model will be usedCorrected residual in-mold stress (CRIMS)Uses state-of-the-art theoretical model to predict thermally and pressure induced residual stress.

Prediction accuracy is improved by comparison with experimental data.Requires shrinkage data, most accurate modelPredictions good in trend and magnitudeUncorrected residual stressSimilar to CRIMS but theoretically predicted shrinkages not corrected with measured dataShrinkage data not requiredPredictions good in trendResidual strainShrinkage data requiredGood in trend, generally good in magnitude but not as accurate as CRIMS
