Ansys Second Development Method and Application in Transient Thermal Simulation

摘要

In transient thermal simulation, automation and customization are the requirement for efficiency of finite element method. This paper proposes a method to enhance the computational performance for ANSYS software. In this process, FORTRAN program is developed to generate the input thermal parameter. Taking APDL (ANSYS Parametric Design Language) as the secondary development for ANSYS, the thermal simulation is executed though the preprocessor, solution and postprocessor modules automatically. Another FORTRAN program is also to analysis the results for the further design. In order to verify the working efficiency and the reliability of the proposed method, the fundamental procedure is applied in computing temperature load of the bridge girder under the thermal effect of the transient sunshine. The method speeds up design and enhances the product the quality and the performance.
