“…One of the most important steps in fi nite element calculations is the meshing i.e. volume separation into a number of smaller elements affecting the computational time and accuracy of the obtained results [14]. Since studied systems have axial symmetry, we have used triangular mesh an extra fi ne element size as a quick and simple way to obtain meshes of high element quality that cover almost the whole geometry.…”

The term electrocautery refers to procedure based on using the heat from an electric current to obtain a desired clinical effects [1][2][3]. The current density required for this procedure is realized by short electric sparks which take place at peak voltages of around 200 V between the electrode and tissue.Once gas is released through the catheter tip, it is ignited through electrical current and an arc is formed leading to the heat destruction and desiccation of the tissue [4]. Although electrocautery had been used for decades, mechanism of burns is poorly understood even in the present day representing an active area of research. Therefore, studies of breakdown enhanced burns can be critically important in clinician understanding what medical and surgical problems may be expected [5].
