In this paper the method of human organ (liver tissue) modelling in the COMSOL environment is presented. Mentioned problems are motivated by the occurrence of negative events during operations utilizing electrosurgery in the tissues with high level of heterogeneity, in particular, the emergence of peroperative complications within abdominal operations. The proposed model of hepatic tissue (respecting its heterogeneous character up to the microstructure of hepatic lobulus) is used for analysis of current field distribution within this tissue. Both complex model of tissue structure (respecting heterogenous structure) and approximated model are mutually compared. The obtained results are exploitable for the analysis of probability of injury formation in sensitive tissue structures, while approximated model shall serve for optimization of complex and time consuming analyses.
