ADSTEFAN is a casting simulation software that accurately simulates the entire casting process providing a quick and reliable solution for real casting problems.

ADSTEFAN is developed by Hitachi Research Laboratory, Japan and has sold over 150 licenses worldwide.

Unique features of ADSTEFAN:

  1. Capable of handling very large mesh size generated from STL model

  2. Prediction of Shrinkage cavity by:
     (a) G/√R: Niyama criterion
     (b) Size and shape estimation

  3. Steady State Die Temperature Prediction
     (a) Die Temperature Calculation
     (b) Unique method to quickly and accurately calculate the Steady State Temperature of the Die via Cyclic Steady state heat balance Method (CSM)

  4. Multiple predictive methods to identify defect size and location taking into consideration the Thermal and Kinematic interactions between the molten metal elements

  5. Accurate Prediction of Thixomolding  Process

  6. Can compute Stress and Structural Deformation
