Computational domain (geometry): a general view, b zoom-in of the ablation area, and c zoom-in of the catheter tip. The subdomains are marked by letters in black circles: a thoracic cavity (infinite elements); b thoracic cavity; c catheter body; d catheter tip; e blood; f myocardium; g pericardium (fat layer); h esophagus; i cooling device wall; j cooling device water. The relevant boundary conditions are marked by numbers in white circles: (1) external boundaries, (2) catheter tip boundaries, (3) left atrium blood inlets, (4) cooling device water inlet
