THERCAST® has a dedicated template for investment casting (precision lost-wax casting).
This will allow you to build the shell directly from the surface of the nest. You will be able to simulate casting by taking into account the thermal and mechanical interactions resulting from the self-radiation that occurs during the process.
In this way, all the complexity of nest cooling is perfectly described by the software. It is also possible to predict the crystalline structure within the alloy in order to estimate grain orientation in the very core of the part.
