A hierarchical structure for automatic meshing and adaptive FEM analysis

A new algorithm for generating automatically, from solid models of mechanical parts, finite element meshes that are organized as spatially addressable quaternary trees (for 2-D work) or octal trees (for 3-D work) is discussed. Because such meshes are inherently hierarchical as well as spatially addressable, they permit efficient substructuring techniques to be used for both global analysis and incremental remeshing and reanalysis. The global and incremental techniques are summarized and some results from an experimental closed loop 2-D system in which meshing, analysis, error evaluation, and remeshing and reanalysis are done automatically and adaptively are presented. The implementation of 3-D work is briefly discussed

Tubercular Sinus of Labia Majora: Rare Case Report

Tuberculosis of the female external genitalia is unusual and primary infection is rare. We report a 50-year-old female patient admitted to Department to Surgery with swelling over left inguinal area with discharging sinus from labia majora to left inguinal crease which was found to be tubercular sinus on histopathology
