Casting Simulation System ADSTEFAN


New Functions / Enhancement of ADSTEFAN Ver.2017

1.Application Blended Element Method to Die Temperature Analysis and Solidification Analysis

Applied blended element method for die temperature analysis and solidification analysis, and improved evaluation accuracy of heat transfer conditions on the contact point of curved surface shaped cast and mold, the evaluation of which was difficult using finite difference method. This enables temperature analysis for rough blended elements with high accuracy in a short period of time, not only for fluid flow but also for die temperature and solidification.

Reducing the gap between analysis and theory

2.X-ray CT Imaging Data Mapping Tool

Photographs a product with X-ray CT imaging equipment, after that, extracts and visualizes void defective parts such as shrinkage and entrapped air by utilizing CT value of the obtained data. This tool quantifies the concordance rate by overlaying and displaying the information about defective parts extracted from image data on the analysis result by ADSTEFAN, and it enables the improvement of comparative verification accuracy. In addition, the extracted shapes from the image data can be also outputted as an STL file.

Analysis Result + Scanned Data by X-ray → Displaying by Overlaying → Calculated Result of Shrinking Area

3.Revision of License Management Policy

Allows for the efficient combined simultaneous execution of differential analysis and parallel calculation with multiple CPUs, and shortens analysis time for design work.
For example, if you had 4 licenses in floating style, you were able to perform analysis with only 4 CPUs in previous version. With ADSTEFAN Ver. 2017, you can use 4 CPUs concurrently on 4 personal computers, which allows for analyses with up to 16 CPUs with 4 licenses.

eg. 4-CPUs License
