Hi Raveendra,nPlease use Maximum Delta frequency per pass to set the level of accuracy of the simulation and try increasing number of passes in case the solution does not converge. You can also increase the number of modes in the solution setup and by plotting the fields you can understand more about the result. Kindly go through the HFSS Help document for detailed information related to Eigen mode solution type. nAll the very best.nBest Regards,nn
