Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0031] The harmonic field-based anisotropic finite element modeling method for the patient-specific sclera provided by the present invention smoothly distributes a regular hexahedral grid on the irregular patient-specific sclera. Among them, the harmonic field is one of the most effective tools for smooth distribution. Its gradient vector field and contour field smooth stream on the surface of the model, and they are perpendicular to each other. They can be use...
