Sand Casting Workspace Highlights

  • Integration of sand properties include permeability, core gas and moisture content
  • Ladle pour with dynamic ladle motion based on pouring cup fill condition
  • Advanced flow solutions deliver accurate gas entrapment and porosity

Workspace Overview

The Sand Casting Workspace provides sand casters with all the tools needed to simulate their filling, solidification, and cooling analyses. The Sand Casting Process Workspace provides the user with a templated design tailored to deliver a clean, easy-to-use setup interface that speaks the language of the casting process engineer. 

Defects in sand castings can often be traced back to the filling stage. FLOW-3D CAST’s extraordinary accuracy in predicting metal flow provides insight into the performance of the rigging system and resulting fill defects. Oxide formation and cold shuts are accurately tracked and located in the final casting. Risers are sized and placed at hot spots while advanced solidification and shrinkage analysis allow for a final, optimized design to be reached in even the most challenging manufacturing environments.


This FLOW-3D CAST simulation shows the thermal activation of an exothermic riser sleeve and the consequent feeding of the casting. For more information about the Gravity Die Casting Workspace, visit
