Shrinkage solidification and porosity are the most common defects. Various investigative techniques exist to distinguish solidification and porosity such as modulus and equi-solidification time and functional criteria as alternative methods of investigation that can be used. Various criteria functions including Niyama Criterion and Franco's Criteria to distinguish solidification and porosity are also alternatives in the discussion of this study. The material that is used for casting is aluminium alloys, that have been analyzed to predict the location of the discovery of solidification and porosity using various software programs such as Procast, Magmasoft, Autocast, Solidcast, in this study the Altair Inspire Cast software was used. The results of this simulation compared to the experimental test results shows no differences with the basic theory and simulation.
