Abstract		Numerical modelling is inevitable approach when modelling electromagnetic problems of complex geometries. Many software products make numerical modelling easy, however several issues have to be considered in order to obtain satisfactory results. Some of those issues affecting the problem of numerical modelling of electric field in liver tissue are described. Numerical method used was finite element method. Special attention was paid to the modelling of needle electrodes and factors that influence the resulting electric field and reaction current in the case of in vivo electroporation. For that purpose the influence of shape of electrodes, their material, diameter and mesh density in region around electrodes was studied Results have shown which simplifications can be employed in modelling of needle electrodes.
