Fast establishment and analysis on three - dimensional finite element of femur

Objective To investigate the operation on files under command stream of Ansys for fast establishment and analysis on three - dimensional finite element of femur.Methods One integrated and fresh femurs in adult corpses was selected,experimental procedure included pretreatment on femurs,high - speed thin layer CT scans with layer of 0.625 mm,compile on mask files,preliminary three - dimensional reconstruction,treatment for surface smoothness,exportation of 3 - D model to Mimics 10.01,partition of grid under command stream of Ansys,achievement of material attributes by empirical formula,further exportation of 3 - D model to Mimics 10.01,finite element was established and analysis on finite element was done. Results Fast establishment on three - dimensional finite element of femoral specimens carried out,simple analysis on finite element achieved.Conclusions Three -dimensional finite element can be established more effectively by applying files under command stream of Ansys.Therefore the number of bone - related medical analysis can be achieved.
