The simultaneous analysis of the magnetic field and stress of the real structure of HL-1 Tokamak of China is presented. Considering the discrete location and varied cross section of the TF coils, the Biot-Savart law is used for the toroidal magnetic field computation. In the FEM stress analysis, 8-20 nodes nonconforming isoparametric elements are adopted, the constraint of the central cylinder is analyzed, and the anisotropy due to layer winding is considered. The magnetic field, stress, and deformation distribution of the TF coils are obtained
