Abstract	A three-dimensional ANSYS RF, Thermal, and Structural analysis has been performed for representative LEDA CCDTL RF structures. Geometry was taken from a Parasolid model that was generated by Los Alamos National Laboratory and represented one cavity structure. SUPERFISH results of this cavity were also provided. The ANSYS RF results were compared to SUPERFISH and to MAFIA models of the same cavity. Enough detail was used in the model to obtain heat load distributions for the coupling slot, coupling cavities, and accelerating cavities. These heat load distributions were then used as input for subsequent thermal analysis. Thermal analysis included coolant elements with heat transport capabilities and temperature dependent properties. Steady state temperature and stress distributions were determined at full field levels. Transient thermal analysis was completed to determine maximum thermal gradients and temperature distributions due to RF cycling. Structural analysis was completed to determine the locations of the model that were beyond yield strength. Plastic stress analysis from a single RF cycle was completed to determine permanent yield of the cavity.
