Development of Calculation Technique for FEM Thermal Simulation Using Virtual Fluid Elements

Autor: Ikuo Tanabe, Hiromi Isobe

Publikováno v: WSEAS TRANSACTIONS ON HEAT AND MASS TRANSFER. 18:8-17

In recent years, CAE (Computer-aided engineering) using FEM (Finite element method) simulations were generally used in the design field. FEM simulations were classified as static implicit and explicit dynamics methods. Particularly FEM simulations us
