Optimization of Turbine Blade Fir Tree Root Geometry Utilizing LS-PrePost in Pre- and Post-Processing

This paper describes geometry parameterization of turbine blade fir tree root prepared in LS-Prepost. The generated FE model utilizes LS-OPT in optimization loop. Simulation results of LS-DYNA implicit solver were used to extract required responses. Some problems arising during solving the task will be discussed in the article.
