Casting simulation software is a popular computer software in foundries. It simulates and analyzes the behaviour of molten metal during the casting process. However, metal casting simulation creates a virtual casting process model. It predicts the behaviour of the metal when it flows into the mould, solidifies, and cools. The simulation uses temperature, fluid dynamics, heat transfer, and solidification. Consequently, it can predict the outcome of the casting process.

There are many reasons why we should use simulation software in metal manufacturing. The most important thing is that this process reduces errors and defects. As a result, we can create quality products from the process. We will discuss these reasons elaborately in the next section of this article.
