CAP (or Casting Analysis Program) is a 3-D finite element analysis program that simulates heat transfer and solidification. It was concieved with die-casting in mind, but the code is so robust and flexible that it can be adapted to any other process by the user. Sand casting, semi-permanent mold, investment, lowpressure, squeeze, and SSM are all processes CAP can simulate with ease.
CAP's specialty is the ability to perform a multi-cyclic analysis. CAP performs calculations so efficiently that many cycles of a manufacturing process (10 or more, however many you need) can be performed within hours. This way you can ensure that your simulations have reached a steady state condition all while giving you results in a timely fashion. CAP results allow you to examine the thermal conditions of not only the casting, but of the die as well. The solidification pattern of the casting can be easily visualized. The location of probable shrinkage defects can be predicted easily with high accuracy.
