A method to identify possible debris clogging area in a machined object includes simulating movement of a plurality of debris particles provided within a modeled object having a plurality of cavities in accordance with a debris clogging evaluation to identify inaccessible areas along the plurality of cavities. The plurality of debris particles is indicative of solid debris and the modeled object is a multidimensional computer designed model. The method further includes determining an egress characteristic of the plurality of cavities based on the simulated movement of the plurality of debris particles. The egress characteristic includes a contact area, an obstruction area, or a combination thereof.
