## Main Question or Discussion Point

hello dear,

I need to calculate the Weyl and Ricci scalars for a given metric. lets assume for a kerr metric. by using the grtensor-II package in maple i am not able to get the results. would anyone help me out. for ordinary metric like schwarzschild metric, However its not working for Kerr metric or metric having form like kerr metric. does anyone have any idea about this??
