      abstract     = {The toroidal field (TF) coil system is one of the most
                      mechanically stressed systems in a tokamak. Structural
                      integrity of the system must be maintained on the global and
                      on the local scale, where the stress state in each conductor
                      jacket as well as in the insulation is to be within
                      structural allowable limits. Solving this task head-on leads
                      to very high computational demands. In this work a
                      methodology for a finite element (FE) detailed analysis of a
                      graded TF coil winding pack (WP) for EU DEMO is presented. A
                      graded WP design option was analyzed in detail in critical
                      locations of the coil, which were identified by an
                      approximate, but very fast approach developed earlier. A
                      comparison with the said approach was made to verify its
                      applicability and limitations. The presented procedure
                      proved to be accurate requiring only moderate computational
                      efforts. The parametric approach allows fast implementation
                      of design changes into the model. The procedure can be used
                      to speed up the assessment of future design iterations of
                      the DEMO TF coil system.},
