A modified VOMAC mesh generation method for image data sampled from an actual object in which mesh resolution can vary locally within the mesh while permitting control of the distortion of cells in the mesh to maintain suitability for performing finite element (or finite volume) analysis on a representation of the object. The method includes computer-implemented instructions that calculate a variable sampling point distribution (SPD) in image data space, the variable SPD having localized variations in SPD within the image data space, and the distribution of sampling points having the same topology as a uniform SPD suitable for obtaining a regular structured is mesh. The method includes generating an indication of the magnitude of cell distortion between the generated mesh and the regular structured mesh Varying the mesh resolution may enable smaller elements to be located in regions of particular interest or activity when subsequently performing analysis using the mesh model. |
