1. A computerized method comprising: reading into a run-time database a model comprising at least one or more solid boundary representation objects modeling a continuous cast product; creating, by a computer application, a connectivity graph for one or more objects modeling a continuous cast product in a model, a node in the connectivity graph representing one solid boundary representation object; checking, by the computer application, whether or not a pour break added by a user via a user interface to a model splits the connectivity graph at least into two separate graphs, a pour break representing a location in which a user intends to break the continuous cast product; and if yes, creating, by the computer application, at least two pour units on the basis of the at least two separate graphs, wherein a pour unit indicates amongst said one or more objects modeling a continuous cast product one or more objects and/or one or more object parts that are intended to be manufactured by a pour, wherein an object part is obtained from an object that is cut into at least two parts by the pour break.
