Cast-Designer Stress Advanced Casting Stress, Distortion & Performance Simulation

Fully coupled flow, thermal, solidification & stress simulation

Introduction

During the casting manufacturing process, components experience complex thermal and mechanical phenomena from molten metal filling, solidification, cooling, and knock-out. Uneven temperature distribution, restricted shrinkage, mould constraints, and phase transformations generate internal stresses that can result in distortion, residual stress, hot tearing, dimensional inaccuracies, and premature failure.

Cast-Designer Stress is an advanced thermo-mechanical simulation solution that accurately reproduces the complete casting manufacturing cycle. Unlike conventional structural FEA, which assumes an ideal finished component, Cast-Designer performs a fully coupled flow, thermal, solidification, and stress simulation, capturing real manufacturing conditions and their influence on final casting quality.

By predicting stress evolution throughout the entire process, foundries and OEMs can optimize casting design, mould design, cooling conditions, and process parameters before production, resulting in higher quality castings with reduced development time and cost.

Cast-Designer Performance CDPE

From Casting Defects to Real Component Performance

Bridging the Gap Between Casting and Performance

Conventional FEA assumes a perfectly sound component, ignoring actual casting defects. Cast-Designer Performance (CDPE) bridges this gap by directly transferring real casting results into structural and fatigue analysis.
Within, Cast-Designer Stress setup, include all additional load conditions just like in generic FEA CAE Software.

CDPE analysis includes following defects in its final results calculations:

  • Shrinkage porosity distribution
  • Gas porosity defects
  • Residual stress fields
  • Microstructural variations
  • Thermal history of the casting

Unique coupling for realistic prediction

Distortion Compensation Solver DCS

Automatic Mould Geometry Compensation

Automatic Mould Geometry Compensation

Cast-Designer Stress includes an advanced Distortion Compensation Solver (DCS) that automatically determines the optimal mould geometry required to achieve the desired final casting dimensions.

By predicting distortion and warpage during casting, DCS calculates the exact compensation needed for the mould geometry, eliminating the need for manual trial-and-error adjustments.
