Abstract
A digital 3D model of a component to be analyzed is obtained. The component includes regularly patterned holes. A first portion of the model is identified. The first portion includes the regularly patterned holes. A second portion of the model is identified. The second portion includes parts of the model lacking the regularly patterned holes. A flow factor of the first portion is determined. The flow factor indicates flow characteristics of fluid flowing through the first portion with the regularly patterned holes. A numerical fluid simulation is performed using a mesh representative of the component geometry. Performing the numerical fluid simulation includes modifying a flow property of the fluid simulation in the first portion based at least in part on the flow factor.
