Abstract: Disclosed are techniques for determining shroud size of a fan. The techniques receive by a computer processing system digital data of a three-dimensional representation of a shroud of an axial fan, partition the received data into a first partition corresponding to a shroud segment and a second partition corresponding to a fan segment. determine a shroud boundary ring for the shroud segment and a viewing angle of the shroud boundary ring, apply to an image of the first partition a beam shooting process to determine the shroud diameter, determine if there are pixels in the image, which have values that produce signals indicating that the pixels are coincident with portions of the shroud and when signal is detected, calculate the shroud diameter. One aspect includes using the determined should size opening for performing a flow simulation.

Abstract: Described are computer-related techniques for determining rotation direction of an axial fan for use in fluid flow simulations. The techniques involve receiving by a computer processing system digital data of a three dimensional representation of an axial fan having plural fan blade, determining by the computer processing system from the data of three dimensional representation of the axial fan, at least a single centerline of a single blade of the axial fan from a two dimensional projection of the axial fan, and calculating by the computer processing system based on the initial valve of fan rotation, an actual value of fan rotational direction.

Abstract: A computer-implemented method is disclosed for creating three-dimensional (3D) variable resolution (VR) region geometries of a modeled object for use in a computer-implemented numerical simulation involving the modeled object. The computer-implemented method includes, inter alia, generating two-dimensional (2D) orthographic views of a 3D modeled object, and identifying edges of each of the 2D orthographic views with a computer-based ray casting method. The computer-based ray casting method includes, for each respective one of the 2D orthographic views, casting virtual rays from different directions toward the 2D orthographic view within a plane of the 2D orthograph view, and detecting an intersection point for each of the virtual rays with an edge of the 2D orthographic view.

Abstract: A computer-implemented method is disclosed that includes automatically determining a ventilation grille opening size estimation for numerical simulation setup automation based on an input in a computer-implemented environment. The computer-implemented method includes creating screenshots of a plurality of computer-rendered images of a three-dimensional grille geometry, with the three-dimensional grille geometry disposed at a different angle of rotation about a first axis, identifying which, if any, of the screenshots has an image of the three-dimensional grille geometry with a total opening value that is larger than every other one of the screenshot three-dimensional grille geometry images, and designating the identified image as a target image for further processing to determine the ventilation grille opening size estimation.
