OPTICast UNIT 8: Setting the Objective Function

Back to OPTICast Menu


The objective is the goal for the optimization process. It is the end result that you are trying to achieve. While you can have many constraints, you can have only one objective. That objective will be to minimize or maximize one of the eleven functions listed on the Obj. Function Tab, shown below:



A common objective will be to maximize the yield, or the ratio of casting weight to poured weight. This is another reason why it is important to create the gating system out of Riser Material. If all metal were made of Casting Material, there would be no change in yield and that type of optimization could not be done.

The Advanced… button on the Obj. Function Tab allows you to set other parameters that control an optimization run. These will be further discussed in Unit 10.
