Casting simulation has become a state of the art tool for the industry. It's a very powerful tool which helps the foundry solve many problems in the production and design department. However for the ...future, there is a clear trend towards end to end virtual manufacturing and prototyping. This means that the current systems and way of working in the casting industry will meet new challenges. The lecture shows this trend, and illustrates this by showing a few samples: Integrating heat treatment and welding stages after casting and linking the resulting simulation directly to the virtual prototyping will change the way of working. Moving towards end to end virtual prototyping is not done over night, this is a process which will take several years, but it's important to understand the challenges which we will meet the next few years.
