A Mesh-Generation Scheme for the Large Helical Device Based on the Structure of Magnetic-Field Lines

We report herein an automated scheme for generating a mesh based on structure of magnetic-field lines. For all angles in the toroidal subdomain, generated by this must not contain broken tetragons. To satisfy requirement, we propose first method to detect elements and second automatically modify elements. use proposed mesh-generation with magneticfield data acquired magnetic axis Large Helical Device at Rax = 3.75 m. The results show that are detected method, transforms into regular
