Casting Problems Finite element computation takes a large amount of computing power. Calculations take hours, even days to run. To reduce the time taken to solve a problem, parallel processing is used.
Several processors work together on a problem, greatly reducing the execution time.
This picture shows the finite element mesh used for a benchmark solidification problem. A mesh decomposition routine is used to automatically split up the mesh in this way. You can see that although all the sections contain equal numbers of elements, some sections are bigger due to bigger elements. The bottom pictures shows the temperature across the four sections after 3 seconds. The more perceptive will notice that each section now contains an area of overlap i.e. that some interface elements are contained in two sections.
