The single crystal turbine blade was usually produced in vacuum furnace by directional solidification technology. The finite element model used for single crystal solidification simulation was complex in structure with difficult pre-process. By the UG secondary development

the parametric modeling of gating system for single crystal turbine blade was implemented

simplifying the gating system design and improving the modeling efficiency and accuracy. Meanwhile

parametric modeling can automatically eliminate coincidence face of gating system to avoid crossed face in the mesh generation

reducing grid error and saving pre-process time.
