Abstract
A method for performing a simulation of an electrosurgical procedure is provided. The method includes the step of generating a three-dimensional model of a medium comprising one or more material regions representing a physical object or a region of the tissue. The method also includes the step of calculating one of an electrical energy solution and a thermal transport solution based on one of a mathematical model and finite element method. The method further includes the step of updating one or more property values of the material region in response to temperature changes based on an empirically derived value, wherein one of the electrical energy solution and the thermal transport solution is updated as a function of the updated property value.
