One of the simplest procedures is the use of modulus values for various casting sections. The modulus method is based on the concept that the freezing time of a casting or a casting section can be approximated by using Chvorinov’s rule. The modulus helps foundry man to determine which riser will be fit for the related Feeding zone
SUTCAST can calculate the thermal module (Simulation module or actual module of cast) instead of geometric

Modulus generated by SUTCAST software

In SUTCAST, however, distribution of the modulus (determined based on modified Chvorinov’s rule) is presented graphically for the entire object.
