One of the really interesting things with Investment casting is that thinwalled near net shaped parts can be produced. In order to find the limits of a certain part or method casting process simulation is a really good tool. With NovaFlow&Solid one can simulate the tendency for cold flows and test different parameters in order to try to get the melt to flow longer. The meshing technology used in NovaFlow&Solid is perfect for thinwalled parts since we use the Finite Volume method in combination with irregular mesh in mold. This makes the simulations accurate at the same time as calculation speed is high. The Speech will cover also importance of shelling process for simulation, shell and casting material as well as use of for example isolation. The program can simulate super-alloys as well as different kinds of steels and aluminium.
