Simulating AM processes are time-consuming action compared with doing casting process, since the AM processes fabricate CAD models upon a layer-by-layer method. Let's consider condition that the model dimensions are roughly large. Thus, the computing time will take a long time to be done. Apart from the time issues, this action definitely has a bad effect on the hardware of the system!

Are there any practical alternatives to solve this problem? In my opinion, the solution may include changing such material properties as density and conductivity in a way differing from those which have been selected for computing casting process, or just simplifying the model and reducing the domain sizes!

Any comments will be appreciated.
